  • Prof: Now what I'd like to do is something that you'll

  • probably cut out because of copyright issues but it's a kind

  • of fun warm-up anyway, so we're going to go ahead and

  • do this and then we'll actually start.

  • I got about a one-minute warm-up here,

  • ladies and gentlemen, and we've got Lynda Paul who's

  • like a Vegas show act.

  • Okay?

  • She's going to warm us up and we're going to get up and we're

  • going to get into it here right off the bat in our exploration

  • of duple and triple meter so here we go, Lynda Paul.

  • Lynda Paul: All right.

  • Those of you in my section will already be familiar with this.

  • Don't give the game away.

  • Everybody stand up.

  • Sorry.

  • Prof: It'll be worth it.

  • Lynda Paul: It's worth it.

  • All right.

  • You have two moves.

  • For the duple meter, you have the march.

  • You may have to turn to the side.

  • Prof: It's okay.

  • They can march.

  • Lynda Paul: And it just goes like this,

  • Feel the duple.

  • Prof: Which foot gets the down beat,

  • right or left?

  • Lynda Paul: Left.

  • Always left.

  • Prof: Okay.

  • Sorry.

  • Didn't know.

  • Lynda Paul: And if you hear a triple,

  • your step is this: down-up-up, down-up-up,

  • down- up-up, down-up-up.

  • This is to get the feel of the duple and the triple.

  • So see what you can do.

  • Prof: You can do this on your test too.

  • >

  • They've got it.

  • >

  • Okay. We got that.

  • >

  • Okay.

  • So that's our warm-up for today.

  • Now from the ridiculous to the sublime, we're going to go to

  • our first slide.

  • And that takes us to the question of sound.

  • We have never really nailed this down, I don't think.

  • When an instrument--any instrument--the piano,

  • plays a note <<plays note>>

  • what you hear is one fundamental pitch.

  • You are also hearing very small amounts of other pitches.

  • Usually, these get charted out into the so-called overtones,

  • thirty-two partials or overtones, and you can see them

  • playing out here .

  • The amount of force in each of those partials--

  • we'll call it the amplitude--of each of the partials,

  • varies according to the acoustical properties of a

  • particular instrument, so that each of these peaks

  • here represents a particular partial,

  • but you can see that they do not decline in any kind of

  • straight decline.

  • Some of them bump up from time to time--more push there,

  • more volume there.

  • So when we hear any particular sound,

  • again, we're hearing an amalgam of many sounds,

  • and the importance of each of these partials in the aggregate

  • of sound is what gives it its particular color.

  • If you've ever worked with a synthesizer: I think,

  • in very simple terms here, what an electronic synthesizer

  • does is play with these.

  • They can push down the seventh partial.

  • They can bring up the ninth partial.

  • They can push down the^( )thirteenth partial and bring up

  • the fifteenth and thereby change the sound of a clarinet into a

  • French horn.

  • They play with these partials on each of these notes,

  • but this is just <<plays note>>

  • one sound with all of these other things mixed in to the

  • medley that produces the quality or timbre of a particular

  • instrument.

  • Okay. That's that point.

  • Now we're going to go on and review a few things that we

  • talked about last lecture.

  • Remember we were talking about beat, which is the regular

  • pulse, the pulse of life, the pulse of music,

  • that comes at regular intervals.

  • We were talking about the subdivision of that pulse,

  • the organizing of that pulse into meters,

  • and that we had this capacity to indicate what the meter was

  • by these numbers: two-four,

  • and three-four for duple and triple meter.

  • Remember we were just demonstrating,

  • listening to the Ravel Bolero.

  • Then we had rhythms superimposed.

  • We had two prominent rhythms up above.

  • Rhythm is simply these patterns, usually repeating

  • patterns, of longs and short that get superimposed as they

  • set up above the basic beat underneath.

  • We also learned from Ravel's Bolero that nobody

  • actually plays the beat-- that's too basic--but our mind,

  • hearing all of these complex rhythms,

  • extrapolates the beat from this complexity.

  • Okay, that by way of a quick review.

  • Now two other terms that we have touched on.

  • What's tempo in music?

  • Yes, gentleman?

  • Student: The pace or the speed of the piece?

  • Prof: It's the pace or speed of the--

  • Student: Piece.

  • Prof: --of the piece, particularly the beat.

  • The beat will do--control--that,

  • so it's the pace or speed of the beat.

  • Thanks very much.

  • We can take a particular--Here I'm conducting in three:

  • one, two, three, one,

  • two, three, one, two,

  • three, one, two, three, one, two,

  • three, and obviously I'm accelerating

  • there.

  • We use the fancy Italian term "accelerando"

  • for that.

  • We could be going with a very fast tempo, three,

  • one, two, three, one, two, three,

  • one, two, three, and slow it down.

  • Obviously, we would be retarding the music,

  • ritardando or a retard at that particular point.

  • All right.

  • With that by the way of background, let's go on to

  • two--what we might call rhythmic devices here--two rhythmic

  • devices.

  • The first is syncopation.

  • We worked a little bit with this last time.

  • For syncopation, let's go to the board over

  • here.

  • If we have a particular rhythm, and this is a rhythm,

  • and here are the beats and the meter underneath,

  • we would be coming along one, two-and,

  • one, two,>.

  • Okay.

  • Obviously, this is the bar of syncopation--we did this in

  • section last week--but you can see >

  • this note is the syncopated note.

  • It's jumping in too early.

  • We expect it to sound there.

  • So what syncopation is is simply the insertion of an

  • impulse, a "hit" if you will,

  • at a metrical place that we do not expect it to be.

  • Usually, the metrical impulse is on the beat.

  • With syncopation the impulse can come suddenly off the beat,

  • and it gives it a little snap or jazzy aspect to the music.

  • We talked about that in the Cole Porter last time.

  • Here is one I remember.

  • A couple of years ago there was a clothing store called TJ Maxx.

  • They had this little jingle out there, >

  • , just a little bit of this, and then you were supposed to

  • say, "TJ Maxx."

  • I'll remember TJ Maxx forever because of this guy's little

  • syncopation.

  • It's in there.

  • We really remember these musical .

  • Think about back in your childhood, your nursery rhymes,

  • the capacity of aural material to be retained.

  • Okay.

  • >

  • Here's beat two.

  • It jumps in too early.

  • This actually I think derives from a Greek word,

  • "synkope," s-y-n-k-o-p-e,

  • synkope.

  • Is that how you pronounce it?

  • But it means to cut short, to cut short and therefore get

  • in a little bit earlier.

  • Now the master of syncopation, of course, in music was Scott

  • Joplin, African American composer writing a lot around

  • the area of St.

  • Louis in the turn of the twentieth century.

  • You know his music from pieces such as "The

  • Entertainer," so let's play just a little bit

  • of "The Entertainer" very slowly,

  • and my question to you is: where is the syncopation?

  • Is it in the left hand of the piano or in the right hand of

  • the piano?

  • Is it in the bass or the melody?

  • >

  • Where's the syncopation?

  • Left hand? Right hand?

  • Right hand.

  • Bass is just going--Well, what is the bass going?

  • >

  • In that fashion, one--It's playing eighth notes,

  • one-and, two-and; it's subdividing the beat

  • whereas the syncopation >

  • --it's there, >

  • and so on.

  • So you're tapping your foot.

  • You're tapping the beat and a lot of the music is coming off

  • the beat.

  • Let's see if we can do that.

  • Let's see if we can create our own syncopated orchestra in

  • here.

  • We've got an example up here.

  • This is the conception of it.

  • Let's see if we can actually execute it.

  • What I'd like you to do: Everybody tap your foot.

  • We're going to do this in four, just for--just because I think

  • it works out better so everybody tap your foot with a four beat.

  • Here we go.

  • One, two, three, four, one, two,

  • three, four, nice and loud.

  • Come on. I want to hear it.

  • Okay.

  • Now take your hand on a chair or your notebook,

  • your computer or whatever, and do syncopation off of that

  • according to this pattern.

  • One, two, ready, go.

  • >

  • Okay. Good.

  • I see Daniel down here has got this nailed.

  • Okay.

  • So that's what syncopation is and it isn't much more difficult

  • than that.

  • The second rhythmic device that we have to be aware of in music

  • we frequently encounter is this concept of the triplet.

  • Now most music that we listen to--and here's a good example

  • because it plays it out so clearly in the melody--

  • most music that we listen to takes the beat--

  • one, two, one, two--and subdivides it into

  • two: one-and, two-and--musicians like this

  • "and" business--

  • one-and, two-and, one-and, two-and--

  • So each quarter note has two eighth notes.

  • We could also take the two eighth notes and divide them

  • into two sixteenth notes and then we get a-one-a-and,

  • a-two-a-and, a-one-a-and,

  • a-two-a-and something like that.

  • >

  • >

  • But of course most music--although it operates that

  • way--not all music continues in that fashion.

  • Oftentimes--occa sionally--occasionally,

  • oftentimes, somewhere between the two--the beat is divided

  • into three.

  • So what I've got here is an example of that.

  • It's actually what we call "My Country 'Tis Of

  • Thee" I think, >

  • , so that's it.

  • I think it's been set by a number of composers over the

  • years.

  • Beethoven set it under the heading of "God Save the

  • King," George the Third or somebody.

  • No, George the Third was probably dead by then.

  • Who was the king of England, let's say, in 1810?

  • Who knows that answer?

  • I don't know it.

  • George the Third would have been dead.

  • Okay.

  • In any event, we're coming along toward the

  • end of it.

  • >

  • So you can hear >

  • , the triplet being inserted, so a triplet is simply

  • insertion of three notes in the place of two,

  • not more complicated than that.

  • Here is what we would expect, >

  • , but we got >.

  • The interesting thing here is that the bass continues along

  • with the duple pattern.

  • The bass is going <<plays piano>>

  • where the upper voice has >.

  • Beethoven could have made that bass go with triplets too.

  • Actually, it's all set up for it.

  • >

  • Both melody and bass could have had a triplet <<plays

  • piano>>

  • but he chose to have the duple in the bass--the triple up

  • above.

  • >

  • Let's see if we can do that, and it's a little bit of a

  • challenge for the performer.

  • Let's see if you can tap your left hand to a duple pattern,

  • one, two, one, two, and then take your right

  • hand and do a triplet against it in a triplet pattern,

  • one, two, ready, go, >

  • , one, two, one, two.

  • It's harder than you think, right, but that's the kind of

  • thing that musicians, particularly percussion

  • players, have to be able to execute.

  • All right.

  • Now an insertion, sort of discursus.

  • We're going to talk a little bit about musical texture.

  • This is discussed in your textbook in chapter six.

  • Texture in music is the dispositions of the musical

  • lines.

  • I was trying to think this morning of an analogy and I

  • thought I came up with a good one.

  • It has to do with tapestries and carpets and things like that

  • where you weave different strands in in different ways,

  • and somewhere in my deep recesses I have these words

  • "wep" (sic) and "warp"

  • or something like that.

  • Does that make any--does that have any resonance to you?

  • No. All right.

  • I think it's out there in weaving.

  • I've got to dig it out.

  • I tried to find it on Google really quick and nothing came

  • up, but I think there is this idea of how you organize a

  • tapestry in that fashion.

  • In any event, in music we have different

  • strands and these strands can be organized in different ways.

  • We simplify it by saying this: that there are three

  • fundamental textures: monophonic texture,

  • homophonic texture, and polyphonic texture.

  • And, to exemplify this, one day it occurred to me well,

  • why not take a tune that everybody knows,

  • "Amazing Grace," and set it in different ways to

  • exemplify these three textures.

  • So that's what we've got on the sheet for today.

  • Everybody's got the sheet there and what I would like to do is

  • just have everyone, all of this--We'll just sing

  • "la" here.

  • We won't sing the text.

  • We'll just sing "Amazing Grace" and we'll kind of

  • start it at pitch.

  • >

  • >

  • Hey, pretty good today.

  • Okay?

  • So we'll start it at pitch there and I'll give you two and

  • then we'll sing "la" and we will exemplify

  • monophonic texture.

  • Here we go, one, sing.

  • >

  • Okay. That's all we have to do.

  • You don't have to read the notes 'cause you've got the

  • sound in your ears, part of your aural memory.

  • So that's monophonic texture, just one pitch.

  • Actually, was it just one pitch?

  • What do you think about that?

  • How many pitches?

  • Let's do this again.

  • We'll sing it again.

  • How many actual frequencies are we generating here?

  • One, sing.

  • >

  • So how many pitches are we generating?

  • Really, two.

  • The gentlemen are singing in one octave.

  • We're singing below middle C >

  • and the ladies are singing up an octave <<plays

  • piano>>

  • but that's still monophonic texture--those notes have the

  • same names.

  • I--We were going <<plays piano>>

  • >

  • so as long as the notes have the same names or it sounds the

  • same, even though there may be octave

  • doubling in there we still think of that as monophonic texture.

  • Lynda, come on up.

  • We're going to exemplify homophonic texture here and we

  • want you to sing the melody and we'll try to do the parts

  • underneath of it.

  • Homophonic texture is where it all lines up pretty much

  • together; all the parts are changing

  • together.

  • One, sing.

  • >

  • One more time and we need- we're going to get our third in.

  • Ready, sing.

  • >

  • How sweet it is.

  • Okay.

  • So that's sweet-sounding homophonic texture,

  • mostly just chords.

  • Thanks, Lynda.

  • Then we can take this and turn it into something a lot more

  • complex with--singing a lot of lines going their own way.

  • This we call polyphony.

  • We also use the word "counterpoint"

  • sort of synonymous with it.

  • So part three down there at the bottom we've got an example of

  • polyphony where I take in the tune and set it against itself a

  • little bit.

  • >

  • So it's just a lot more complex, a lot of independent

  • lines going on up above.

  • Think of one line.

  • Think of a group of lines.

  • Here's one sound.

  • >

  • Here's a group of sounds, >

  • different pitches and actually three different pitches in

  • there, as opposed to just one

  • pitch--one pitch, three pitches or three or four

  • pitches, moving in different ways,

  • kind of independent rhythmic chords,

  • so that's the difference between monophonic,

  • homophonic and polyphonic texture.

  • Now we're going to turn--focus here just a bit more on

  • polyphonic texture because there are two types of polyphonic

  • texture.

  • The first we'll call imitative polyphonic texture,

  • and here in "Amazing Grace" we really do have

  • imitative polyphonic texture because you--

  • as you can see, we have in the bass--

  • there in bar two--the bass imitating the upper part

  • >

  • and then toward the end there in bar thirteen <<plays

  • piano>>

  • the bass and I've added an extra note.

  • It occurred to me here I could take that theme and turn it

  • upside down against itself and it would work.

  • >

  • Yeah.

  • So that's called musical inversion.

  • Bach would like that.

  • He likes these kind of mind games with music.

  • So it's complex stuff, this polyphony or this

  • counterpoint.

  • So this is imitative counterpoint because there's one

  • idea that keeps coming back and back and back.

  • Now there's another kind of counterpoint called "free

  • counterpoint" where it's highly independent

  • lines are sounding but they're not imitating one another.

  • Let's listen to just a section of this.

  • We should have this.

  • It's Louis Armstrong and we'll talk more about Louis Armstrong

  • as we proceed here.

  • So listen to a good example of non-imitative texture,

  • polyphonic texture.

  • >

  • Pretty cool stuff, huh?

  • Where was Louis Armstrong from?

  • Student: Chicago.

  • Prof: Chicago?

  • Actually, he did his recordings in Chicago, but he wasn't from

  • Chicago.

  • Where's the heart and soul of jazz in America?

  • New Orleans. Right. Yeah.

  • That's why it's so important culturally for the history of

  • the United States.

  • So what we want to do now is to begin to think about counting

  • measures, and we're going to do this by

  • staying with this piece of Louis Armstrong here,

  • and we need to be able to count measures so that we can figure

  • out the syntax of music.

  • Music is a language and it is made up of a syntax,

  • and syntax, you know, consists of phrases and the

  • order in which those phrases occur.

  • But maybe even before we can recognize the syntax of music,

  • we have to figure out what a phrase is.

  • So to do that we've got to be able to count measures.

  • How do we do this?

  • Well, musicians, again, have developed the

  • following sort of process.

  • Let's say oftentimes orchestral musicians, they're sitting there

  • and they're not playing so they have to be able to count for a

  • long period of time.

  • So they'd be going along in this fashion--let's say it's

  • duple--one-two, two-two, three-two,

  • four-two.

  • They're just adding integers on each down beat.

  • It's a very simple idea.

  • So that's what we're going to do.

  • Think of these poor French horn players in the orchestra.

  • They play so rarely, and then it's so important when

  • they do play, they'll be out there:

  • seventy-eight-two, seventy-nine-two,

  • eighty-two, eighty-one-two-- You've got to count forever.

  • We won't have to count quite that long,

  • but even before we count, we've got to figure out what

  • the meter of the music is, so let's start with that now.

  • What's the--Let's go back or I guess we're going to go to the

  • beginning.

  • What's the meter of this piece?

  • And then we'll go ahead and count some measures.

  • >

  • So it's duple meter.

  • Our brain has got all that stuff coming in there and we're

  • probably focusing a lot on the bass and "boom,

  • boom," the tuba that's playing there.

  • So let's go on now.

  • We're going to hear Louis Armstrong himself play.

  • What instrument did Louis Armstrong play?

  • Student: Trumpet.

  • Prof: Trumpet, yeah, and he had this wonderful

  • rich sound but boy, it was a big,

  • huge sound, kind of the ultimate in-your-face trumpet

  • player.

  • So we're going to hear a solo by Louis Armstrong now and let's

  • count along once the phrase begins.

  • I'll get you started and then you count the measures.

  • Here we go.

  • >

  • Here we go. Ready.

  • >

  • One-two, two-two.

  • Go ahead.

  • And then he disappears.

  • So how many bars did you count there?

  • How long was the phrase that Louis Armstrong played?

  • Student: Eight measures.

  • Prof: Eight measures?

  • Everybody agree with that?

  • Anybody say seven?

  • Better say eight in music.

  • Asymmetry is not the norm in music <<music

  • playing>>

  • so eight's a good bet there.

  • Let's go back and hear another solo.

  • It's a wonderful clarinet solo by someone named Johnny Dodds--

  • long dead of course--but it's one of the most beautiful,

  • incredible clarinet solos you'll ever want to hear.

  • How long is this solo?

  • How long is this phrase here by Johnny Dodds?

  • >

  • Here we go: one-two, two-two.

  • >

  • Student: Sixteen.

  • Prof: Sixteen, so twice as long,

  • but that's sort of good news.

  • A lot of music is made up of these two-four and four-four

  • sorts of aggregates.

  • And then we'll just go on to listen to the end of this where

  • everybody's in.

  • It's hard to know again what the melody is or what the phrase

  • is here.

  • It's just everybody playing.

  • Remember: are they using music here?

  • Could these gentlemen read music?

  • It's not clear that this particular group could.

  • It's--I'm sure that Louis Armstrong would read some music,

  • but again it would just get in the way of what he's doing.

  • All of this was aurally transmitted and aurally taught.

  • So let's listen to the end of it.

  • It's called "Willie the Weeper."

  • You're going to have it as one of your listening exercises.

  • Let's listen to the end of it here.

  • >

  • Now here we go with our phrase.

  • >

  • We used to call that in--remember when--anybody in

  • high school band here?

  • What do you call that "boom"

  • at the end?

  • Do you still call it that, "stinger"

  • at the end, sort of a syncopated bounce at the end of

  • the thing?

  • How long was that particular phrase?

  • Sixteen bars there, again, and a perfect example of

  • free counterpoint.

  • You've got the trombone, the clarinet,

  • the trumpet.

  • They're all just doing their own thing in the context of the

  • harmonies that are playing out here, and it's just magical I

  • think.

  • What happy music. Right?

  • How could you possibly be sad when listening to that kind of

  • music?

  • And then they play this kind of music coming back from funerals.

  • You're dancing in to heaven.

  • It's that kind of thing, yeah.

  • I bet there's heavenly music of that sort.

  • Okay.

  • Now let's go on to another thing that we'll want to be

  • doing here and that I guess is taking a little bit of rhythmic

  • dictation, writing down some simple

  • rhythms.

  • How are we going to do this?

  • Why do we want to do this?

  • Because we want to remember things.

  • Wolfgang Amadeus Mozart had a very good musical memory.

  • There are lots of stories about Mozart's musical memory.

  • In 1777, he was in the town of Mannheim.

  • He heard a string quartet by a man named Cambini.

  • It was never published.

  • There are no recordings of it.

  • Mozart goes to Paris.

  • About six months later he bumps into Cambini.

  • He says, "Oh, Cambini.

  • I remember you.

  • We--I heard your string quartet in Mannheim."

  • And he sits down at the piano and plays the thing.

  • He didn't have-he wasn't studying this thing.

  • He wasn't trying to memorize it.

  • He heard it just once.

  • Six months later he could remember the whole movement of a

  • string quartet.

  • Another famous story: In 1770, he goes in to Rome,

  • into the Sistine Chapel.

  • It's Holy Week.

  • He goes to hear the well-known Miserere of Allegri,

  • Gregorio Allegri.

  • You're not supposed to copy this piece because it's supposed

  • to be only performed in the Sistine Chapel.

  • Mozart goes in.

  • He hears it.

  • He and his father walk back to the inn where they are staying.

  • He writes down this four- to five-minute composition note for

  • note in just one sitting.

  • That's pretty scary.

  • Wouldn't it be?

  • I--You're just off on a different planet in terms of

  • your capacity to process aural material, but we--I can't do

  • that.

  • I couldn't begin to do that.

  • How much can I hear?

  • Two seconds, three seconds,

  • four seconds.

  • I could probably remember that.

  • And he's hearing multiple parts, not just melody.

  • So we have to come up--we mortals--

  • have to come up with some other device,

  • and our device to remember things is to try to write it

  • down because my premise here is, if you can write music down

  • clearly you are hearing it, clearly, and you would have a

  • better chance of remembering it if you could write it down.

  • So it just helps us focus on these isolated events.

  • We're not going to try to remember everything in

  • music--too complex.

  • We're going to focus on the simple, salient things--could be

  • an instrument, could be an important rhythm.

  • So let's listen to some more music of Musorgsky here,

  • Modest Musorgsky.

  • We had that very interesting piece last time,

  • "Polish Oxcart" where he used this principle of

  • low sounds produce sound waves that stay forever and we hear

  • those low sounds first and last.

  • So here we're going to hear another piece from that

  • Pictures at an Exhibition.

  • It's called "Great Gate of Kiev" so let's listen to a

  • little of this, 1874, I believe,

  • or 1870s surely, and let's listen to a bit of it

  • and then we're going to focus just on the rhythm.

  • >

  • Okay. Start conducting.

  • >

  • All right. Good.

  • Very interesting.

  • There are two possible explanations to this.

  • Some of you are going with a very slow tempo:

  • one-two, one-two.

  • Others are a bit uncomfortable with that,

  • >.

  • They're going twice as fast.

  • Which is correct?

  • Well, for our purposes, both are correct and we'll know

  • how to figure this out on tests.

  • If you say--you've got two measures here and you're writing

  • particular symbols, we'll know that you heard this

  • with the slower possibility.

  • If you've got four measures and different symbols,

  • you're clearly subdividing the beat but hearing that as the

  • beat.

  • So all I'm really interested in here is the idea that we have a

  • duple meter.

  • Having said that, let's assume that we do have

  • the slower tempo here, one--Let me play a little bit

  • at the piano.

  • >

  • So your hand should be moving rather slowly.

  • Let's all sing it.

  • >

  • Okay.

  • So that's the music.

  • Now having done this setup, if you think about it,

  • and think about the fact that--what note symbol gets the

  • beat in our course--quarter note, okay.

  • >

  • So every gesture of the hand is going to be the equivalent of a

  • quarter note.

  • What's going to be my first note symbol?

  • >

  • The half note.

  • Here's one gesture; here's another gesture.

  • >

  • Okay?

  • So I've got you going there.

  • You take your piece of paper now.

  • If you want to hum the piece quietly to yourself,

  • that's fine; that's good.

  • If I hear lots of buzzing out there,

  • that means you're into it, so hum the piece a little bit

  • to yourself, Musorgsky's "Great Gate of

  • Kiev" here and Pictures at an Exhibition and see if

  • you can write down those particular symbols.

  • >

  • Okay. Let's sing it again.

  • Here we go.

  • Ready, go.

  • >

  • Let's focus >

  • just on that unit, that measure.

  • >

  • Having trouble with this?

  • Look at this.

  • >

  • One gesture, two notes, two pitches.

  • >

  • What should those--what should the rhythmic value of those two

  • pitches be?

  • >

  • Yeah, two within one beat would give us eighth notes.

  • Okay.

  • So let's finish it off one more time.

  • Here we go. Ready, go.

  • >

  • So what should we write up here?

  • I lost my black marker but that doesn't matter.

  • >

  • What should I write next?

  • Well, those are the two eighth notes we were talking about.

  • >

  • Then what?

  • >

  • One note for each gesture and we've just done a rhythmic

  • dictation of the beginning of Musorgsky's "Great Gate of

  • Kiev" from Pictures at an Exhibition.

  • So you're not going to forget this particular melody and it's

  • because it sounds so grand.

  • There's another reason we're not going to forget it,

  • if you've focused on it in that way.

  • So when later on we're dealing with symphonies and things like

  • that you may be sketching little motivic snippets,

  • little rhythmic snippets, that you'll file away.

  • All right.

  • Let's listen a little bit more to the Musorgsky and then we're

  • going to go on, just a bit more to the next

  • excerpt, and here's my question for you.

  • You're going to hear the violins play a running scale,

  • >.

  • If our beat is this, >

  • what note values are in the music of the violinists at this

  • particular moment?

  • You don't even have to see the score.

  • You can figure it out.

  • >

  • So what note value are they playing there?

  • Student: Sixteenth.

  • Prof: Sixteenth because we've got four impulses

  • >

  • for each beat.

  • Let's go on to the next here now--a couple of questions we

  • could ask.

  • The theme comes back.

  • We're going to listen to it again.

  • What string technique are the violins using at this particular

  • moment and then <<music playing>>

  • what rhythmic device does the trumpet insert?

  • So let's focus on the strings first.

  • We may hear this twice.

  • >

  • Okay. What are they doing there?

  • What are they playing there?

  • Student: Tremolo?

  • Prof: Tremolo, just kind of filler.

  • Right?

  • We need a big sound here.

  • Let's get the violins to fill in sonic space.

  • It's kind of--there must be something in cooking like

  • that--use cornstarch or something, a filler--I don't

  • know--just to make--give something body.

  • So this is kind of giving the music body here.

  • It's not of particular interest melodically.

  • Now when the trumpet enters something of interest happens.

  • What rhythmic device is the trumpet inserting?

  • So let's go back to the same spot.

  • We'll hear the tremolo and then the trumpet.

  • Here we go.

  • Notice the tempo is slowed down a bit here also.

  • >

  • So what did the trumpet insert, what rhythmic device?

  • Student: Triplets..

  • Prof: Triplets.

  • >

  • So focusing on rhythm can tell us a lot about the detail going

  • on in pop music or in classical music in particular.

  • Now I'd like to end--I think I have a few minutes here--I'd

  • like to end with a particular piece.

  • We've talked about Mozart before and we're going to go on

  • now to talk about Mozart's Requiem.

  • It's a Requiem mass.

  • What's a mass?

  • Well, a mass is a genre of music.

  • Obviously, it's a religious service as well,

  • but it's a genre of music like the symphony or the concerto.

  • Bach wrote a mass, Mozart wrote many masses,

  • Beethoven wrote two important masses and so on.

  • So it's a genre of music.

  • The Requiem mass is a particular kind of mass.

  • It's a mass, obviously, for death and burial

  • and the commemoration of those who have died.

  • Unlike the regular mass, the Requiem mass has a very

  • special movement associated with it.

  • It's called the "Dies irae"--the "Day of

  • Wrath."

  • It's just a long, long text that's set to music

  • but that text is drawn from "Apocalypse,"

  • the images of "Apocalypse."

  • If you ever read the Book of Apocalypse--

  • or Revelation--you know it's hellfire and brimstone,

  • the day of judgment, damnation--election into the

  • group of the blessed, and so on.

  • So it's a very vivid kind of text.

  • Now I was going to put that text up on the board and,

  • to be honest with you, I forgot to do that,

  • so I'm going to have to see if I can remember this text:

  • We're going to focus now on two sections of this work:

  • the "Confutatis" and the "Lacrimosa dies

  • illa."

  • They are both subsets of the "Dies irae."

  • The "Confutatis" go-- The text is as follows:

  • "Confutatis maledictis, voca--voca--me cum

  • benedictis."

  • So on one side here we've got the "confutatis

  • maledictis."

  • These are the damned.

  • On the other side, we've got "voca--voca me

  • cum benedictis."

  • These are the blessed. Okay?

  • Ever been to a medieval cathedral?

  • You walk in the front door, Christ in majesty--

  • on the left side are the damned writhing and on the right side

  • are the blessed looking a good deal happier.

  • So Mozart may have had this image in mind of the damned and

  • the left, but he sure was able to set

  • it--this text-- through music by using a couple

  • of devices.

  • The first of these is rhythmic, so we're going to turn now--I

  • guess we'll turn off the lights and we're going to go to a

  • couple of slides here.

  • Let's take a look at the rhythm he associates with the damned.

  • What kind of rhythm do we get with the damned?

  • Well, where would you expect to find the damned?

  • In the high register or the low registers?

  • The low registers, and they're way down in the

  • twenty-ninth canto of hell or somewhere.

  • So here's what we find, and as you can see there--is

  • this bass rhythm moving slowly or quickly?

  • Very quickly.

  • It's going like this >

  • and so on.

  • It's also doing what?

  • Going up or down?

  • Student: Up..

  • Prof: Up.

  • It keeps rising up.

  • This builds tension.

  • Okay?

  • Are these happy folks singing there?

  • Well, they've got this kind of music.

  • >

  • Is this conjunct music--step-wise music--or

  • jumpy, skippy music?

  • Pretty skippy.

  • And is it consonant music or dissonant music?

  • >

  • Very dissonant music.

  • Is it major or minor?

  • >

  • Minor.

  • Okay, so I'd say he's got about four things he's working with

  • here.

  • The rhythm is very important.

  • Now eventually the elect come in.

  • And their rhythm--what do they have?

  • Are they high or low?

  • Well, they're way up high.

  • You can see them in the sopranos and altos up there

  • >

  • and they just sit there on that pitch--a long note:

  • one, two, three, four.

  • >

  • I don't have the next page.

  • >

  • That's what they do.

  • It's consonant, it's in major,

  • it's high and, most important,

  • the rhythm is very uncomplicated.

  • The notes are long and slow.

  • So let's listen to Mozart's depiction of hell and heaven

  • here.

  • >

  • Heaven.

  • >

  • And then he goes back to hell and then back up to heaven--goes

  • back and forth between these two rhythmically very different

  • concepts.

  • Now Mozart died in December, 1791.

  • He wasn't planning on dying.

  • Actually, his death came rather suddenly and he was working on a

  • requiem that someone had commissioned from him under

  • rather mysterious circumstances and he began to think of it as

  • his own requiem, and indeed, he didn't actually

  • finish it.

  • Here, from the Austrian National Library where I was

  • last summer photographing and having a wonderful time,

  • is the last page of the Mozart--that Mozart ever wrote

  • here.

  • This is the "Lacrimosa,"

  • and sort of breaking off--and he doesn't finish this

  • particular movement.

  • It's the last movement that he was working on,

  • but he has a student there, Franz Xaver Suessmayr,

  • and Suessmayr was given instructions and probably

  • sketched pages as well, as to how to finish this.

  • So Mozart was able to finish it and it looks--or--excuse me.

  • Suessmayr was able to finish it, and it looks like this.

  • Here we have a score of it--of the complete piece,

  • and there are just a couple of details that I want to point out

  • here.

  • It begins with what I always hear as a kind of funeral

  • cortege idea.

  • Of course, it's in minor >

  • and the voices will come in, but the bass is going,

  • >

  • sort of plodding along in a basic duple but with a triple

  • subdivision underneath of that.

  • And then at the words you can see--

  • well, maybe you can't see--but the text is "On that

  • terrible sorrowful day"-- we have the words--where is

  • it?--"Qua resurget ex favilla"--

  • "on which resurgent will come forth--

  • resurgent, will come up out of the ashes."

  • "Homo reus,"-- "the just person to be

  • judged," and notice how it's like the

  • coffin's opening up and here comes Mozart's soprano line up

  • here.

  • >

  • Wow.

  • What a run, but it's all kind of text depiction here.

  • And then in the next page he's going to take that same rising

  • line and assign it to the basses.

  • Then we have a change of text here.

  • "Huic ergo parce, Deus," "Therefore

  • save, God."

  • "Parce" ;--imperative--"save

  • us."

  • "Pie Jesu, Jesu Domine,"

  • and at that text what he does is shift from this dark minor

  • >

  • right over the words "Jesu,"

  • he's already <<plays piano>>

  • in a sweet major, and then he'll work his way

  • back to <<plays piano>>

  • the minor as the funeral cortege continues,

  • and this time the line will go down instead of rising up.

  • So this goes on for a while.

  • We're going to start--we're going to listen to the entire

  • movement.

  • It runs about our minutes so bear with me here.

  • We'll run about thirty seconds over as we listen to the

  • "Lacrimosa" out of the "Dies

  • irae" out of the Requiem Mass of Wolfgang Amadeus

  • Mozart written in Vienna seventeen 1791.

  • >

  • Okay, cortege.

  • >

  • Now the basses.

  • >

  • Now the quiet prayer.

  • >

  • Change to major.

  • >

  • Now the modulation--change of key from major to--back to minor

  • as the cortege will start up again and then we--

  • >

  • A nice clarinet sound there and here comes our cortege with the

  • bass.

  • >

  • Now just a final close, a cadence.

  • >

  • So that's the last music of Wolfgang Amadeus Mozart and his

  • pupil, Suessmayr, and--not to leave

  • you in a somber mood-- let's listen to Louis Armstrong

  • as we go out.

  • Okay?

  • >

  • Dancing to heaven.

Prof: Now what I'd like to do is something that you'll
