The harmonic series in music | Assaff Weisman | TEDxNYIT

This talk refers to a Bobby Mcferrin demonstration called "Watch me play the audience"(www.ted.com/talks/bobby_mcferr..., and explores the universality of music by examining the naturally--occurring phenomenon of the harmonic series. It makes use of a demonstration of the principles of the harmonic series, presented by Leonard Bernstein as part of his Norton Lectures at Harvard University in 1973.
Pianist Assaff Weisman’s solo and chamber music performances have taken him to some of the major venues in Europe, the Middle East, and the Americas; from Lincoln Center and Carnegie Hall in New York, to the Beethovenhalle in Bonn, and Rudolfinum in Prague. He is frequently heard on radio stations across the United States, in music ranging from Bach to the present day. His 2002 release of an all-Schubert recording for Yamaha’s “NYC Rising Star” series quickly became one of its best sellers. An avid chamber musician, Mr. Weisman has collaborated with Isidore Cohen, Michael Tree, Samuel Rhodes, and Peter Wiley, among others, and has taken part in the Aspen Music Festival, Campos do Jordão (Brazil), Lima Chamber Music Festival (Peru), The Music Festival of the Hamptons, and Verbier (Switzerland). He is a founding member, and the Executive Director of the award-winning Israeli Chamber Project, with which he has toured and recorded since 2008. Mr. Weisman is a graduate of The Juilliard School, where he received both his Bachelor’s and Master’s degrees as a student of Herbert Stessin, and where he now is a member of the Evening Division piano faculty. Prior to his studies in New York, Mr. Weisman worked with Professor Victor Derevianko in Israel, where he was a winner of the America-Israel Cultural Foundation Scholarships. Mr. Weisman is a Yamaha Artist.

This lecture is just blatant misinformation. Random musicians who studied at a conservatory are *NOT* experts on sociology or psychology. We don't recognize the major pentatonic scale because of the harmonic series; we recognize it because of cultural conditioning. If this guy's logic weren't absurdly flawed, then we would be singing along to the actual harmonic series and not the pentatonic scale. This is not the case, however, and if you took somebody who had never heard any music in their life, they would never be able to predict the pitches of the major pentatonic scale.

Great lecture! I teach piano and I always teach music theory, not just how to read sheet music. I introduce theory by doing what you did and calling it the Chord of Nature, as it is commonly called. To my technically minded students, it lets them understand why the dominant is as important as the tonic in establishing the key. In fact, when a pianist accompanies a singer, the pianist usually plays an arpeggio of the dominant chord to give the singer the key!

[@billwesley]

[@Pianodog]

Technically, the 7th harmonic is closer to Bb than A but it does exist in the cracks. The pentatonic scale uses the pitches CDEGA because a stack of the third over tone produces it not because of the harmonic series. A pentatonic built from the harmonic series would sound quite different.

[@MarkCosgrave]

Pianodog Mad. Do you know of any resources that go through how the Pentatonic is formed the way you speak? I'm really interested in how scales are formed, and how different tuning systems have come about at the moment. And I'd love to know more about what you speak. It's strange because I would have thought the way he is describing it would make the most sense, in that the brain just picks up on the next most clearly recognisable consonant resonant frequency it hears? So when the tonic note is played, your brain just hears those other frequencies resonating underneath, and goes, ok that's the 'ladder' im going to take going upwards from here. Even though your not consciously hearing those resonating frequencies, on some level you are, and to your brain they appear as the most logical steps forward. To me, it wouldn't' be that your brain 'constructs' so much a pentatonic scale from a stack of third overtones, like we might construct the diatonic scale from a stack of 5ths or so on. It doesn't do that kind of calculating, like we do when we try to make/construct a scale. It just 'hears' what it hears, and naturally goes from there. It is doing calculations of course, but these are inbuilt they are from nature, where as constructing a scale from stacks is more of a 'human' endeavour. What do you think?

[@Pianodog]

Ok cool, glad you find this interesting. The pentatonic scale is built from a stack of fifths as is the 7 tone diatonic/major/minor scale. Tuning (called pythagorean tuning) originally was designed to favor the tuning of fifths so that these scales would sound best. However, tuning is a tricky subject and every improvement on one thing will ultimately hurt something else. The problem with pythagorean tuning is that is makes intervals like thirds and sixths and even fourths sound worse. This CAN be ok depending on what you want in a tuning system. But for whatever reason, the people at the time felt that they wanted certain consonances. 12 ET was formed I think by chinese originally which is why the black keys on the piano literally are pretty close to ancient many chinese scales. That is, without having alot more notes involved. Real chinese scales from ancient times apparently has flatter sevenths. So like if you play C D F G Bb on the piano, the ancient scale most likely had a note flatter than Bb but not quite A. I'm not sure if this is the seventh harmonic, but it was closer to that than to 12 ET. A pentatonic scale directly built from the harmonic series would contain the seventh harmonic ( just below a minor seventh) and fifth harmonic (just below a major third) and would sound much more rich harmonically, the tradeoff, if that fifths wouldn't be in tune except for the fifth built on the first degree and perhaps another place as well. So the harmonic series in terms of 12 ET is Root - perfect Fifth - below major Third - below Minor seventh - TINY BIT FLAT Major ninth. Morale of the story is that 12 ET is a small system that tunes fifths and fourths really well but kinda sucks for thirds and the seventh harmonic is barely approximated at all since it's REALLY SHARP from a good seventh harmonic. Think of it this way, you know the way a fifth kinda growls? Well a decent tuned major third and minor seventh would also growl and sound crunchy which is really cool. What's weird though is thai music which uses a seven equal tuning system. That is, the octave is divided into seven equal steps producing a wildly different sounding scale which is more rough yet very pleasing melodically. There is no recorded history as to the reason for this scale, just theories. There is a facebook group all about this that is extremely active. Come check it out facebook.com/groups/xenharmonic2/ :)

[@Pianodog]

Also another thing you may not realize and may seem strange, tuning often is a mathematical thing much more than an intuitional thing. Most tuning was derived by math not by how good it sounds. Really weird but true.

[@MarkCosgrave]

Pianodog Thanks to my recent research, I almost get what you are saying about the tuning systems, I'm still struggling with it though. But I think what this man is getting at, and more so what Bobby Mcferrin was getting at was to do with the natural tendency for the human being to identify a pentatonic scale. This is totally separate from tuning instruments, and systems, which came along much later. Were talking here about the human voice, the innate scale that a human being would have sung you, prior to any deliberately constructed tuning systems.

[@MarkCosgrave]

***** In essence, the 'pentatonic' scale exists in nature simply because after the fundamental (and removing octave equivalence) the notes from which it is 'made up from' are the next 'loudest' / discernible frequencies the human brain will hear within the tonic note. It is not constructed, it is implicit in the sound of the tonic note. Later when we get into tuning instruments, and systems, we speak of 'constructing' a pentatonic scale.

[@phisonicssoundimmersiontec917]

It is important to note that he was imprecise in his claims about the harmonic series. The harmonic series is a universal wave phenomenon only for bounded one-dimensional wave paths. Some of our musical instruments approximate one-dimensional wave paths closely enough to be considered roughly as such (like strings and tubes of air). The harmonic series is the special one-dimensional case of the more general modal series, which varies according to the geometry and material characteristics of each vibrating thing. In our very-much-not-one-dimensional instruments (drums, gongs, vibraphones, etc) we have these more complex, non-harmonic, modal series. In short, the closer to one-dimensional our vibrating system is, the closer it's vibrational modes approximate the harmonic series. And vice-versa. Hopefully this clarifies somewhat for any interested readers.

Interestingly enough, the note between A and Bb is not because of how the pianos are tuned but because that is how the harmonic sequence naturally progresses.

[@xanderinsall3764]

I think he's getting at the fact that the reason it isn't a conventional note is because the piano is tuned to equal temperament tuning.

[@violaguy90]

Strongly disagree with his theory of getting the pentatonic scale from partials 3-4-5-6-8. In my opinion, it is much more basic: the perfect 5th (from partials 1-2), iterated 5 times, then placed in the same octave. The resulting pentatonic scale is much more in tune, as well

[@MatteoVicino]

Does this guy know his left from his right???

[@tomdowad5494]

I think many of the comments here are too hard on the guy. Its a good talk. It happens to be true so we should expect this explanation will have been given before. He's referring to the major pentatonic, he failed to mention that the blues scale is a minor pentatonic. I think it is equally important to understand how the cycle of 5ths generates the chromatic scale. But the talk is for people who don't know music theory so understandable he didn't cover that.

[@Pseudify]

That test he does with the resonating overtones is even more impactful if you, say, hold down the G and play a B or C# first. You don’t hear that resonance until a C is played.

[@Shermanbay]

Excellent lecture! As one whose BA is in music theory & composition, I use a similar demonstration with my students showing the overtones. It works better in a small classroom! I have a slight nitpick, however. This lecture shows a Western bias. Historic Asian music, at least until the modern merging of cultures, does not exhibit the pentatonic structure nearly as much (if at all), but often uses harmony based on third and quarter-steps, incompatible with a piano. That suggests a cultural assimilation, not a universal biology.

[@leahanderson7504]

Weisman is wrong about the "universal acoustic phenomenon" . This particular overtone series does not happen everywhere in all "regular" instruments. This series he references mainly applies to Western music with Western instruments. Take for example a gong from a Balinese gamelan. The overtone series we would hear would NOT be in the root-octave-fifth-fourth-[etc.] pattern we are taught to hear, but instead a different series altogether. I am currently studying the different overtone series for idiophones vs chordophones vs membanophones vs aerophones and so on. The overtone series mentioned in this video applies to aerophones (wind instruments) and chordophones (strings), even some idiophones but definitely not all! (i.e. Xylos and Marimbas have a different overtone series than the "universal" one Weisman claims all instruments have. Take a listen for yourself!). I just wanted to share because I feel like we Western musicians have been taught incorrectly. And I realize now that only those who have studied the world (ethnomusicologists) know how ignorant western culture is to everywhere else. I know it was hard for me to even grasp that there were other overtone series since I've only been taught about THE overtone series, as opposed to ONE of many overtone series. I was ignorant, but I'm still discovering more about how certain instruments have a unique overtone series than other instruments within the same family. It's a very interesting topic! Don't take my word for it, go out and see for yourself! But please don't stay in the dark. Hope this helped somebody out there!

[@Justinwhat1]

Leah Anderson Cool info. Thanks. Will check that out.

[@MrNickdino]

Leah Anderson , allright! i've been speculating what you've shared here. Can i get in touch with you?

[@Modicto]

And to add just a small bit of irony, the piano - of all western non-percussive instruments - shows the strongest deviation from the described integer harmonic overtone scheme. For example, stiff strings (most notably in the lower keys) are severely affected by wave dispersion which causes different frequencies to propagate with different speeds in the string, skewing the distribution of overtones. This is somewhat compensated by tuning the piano "out of tune" so to say by stretching the tuning so that a good portion of harmonic components overlap. For example, a Steinway Model D can have 60 cents tuning deviation when comparing the lowest and highest note. www.simonhendry.co.uk/wp/wp-content/uploads/2012/08/inharmonicity.pdf

[@didjesbydan]

Integer harmonics are a physical phenomenon of periodic oscillators and are ubiquitous in nature--not just in musical instruments which may or may not be tuned to the harmonic series. It isn't merely a cultural thing we are "taught to hear".

[@teddydunn3513]

The pentatonic scale comes from stacking fifth, not really from the harmonic series. The seventh harmonic is usually interpreted as a minor seventh. I promise you, our perception of the pentatonic scale comes from cultural conditioning, not the harmonic series.

[@fromchomleystreet]

The harmonic series really doesn’t intuitively explain why people default to the pentatonic scale in McFerrin’s experiment, or why it is so ubiquitous across cultures. It might explain why they guess at the major third and perfect fifth, but why the major sixth? The first five unique notes to appear in the harmonic series are identical to the common pentatonic scale with one crucial difference - the sixth is replaced by the minor seventh. So one would think if the harmonic series caused cultures all round the world to use a particular pentatonic scale, then that pentatonic scale would include the minor seventh, not the major sixth. (Edit) I now see he’s interpreting the note I call a minor seventh as being somewhere between a minor seventh and a major sixth, and he’s arbitrarily defaulting to the latter. But the note that naturally occurs in the harmonic series is clearly closer to a minor seventh than it is to a major sixth, so why would the entire world default to the latter if it is purely based on the harmonic series?

The animal bones were found to be canine tooth pierced bones and the spacing happened to excite some non-science thinking, there was no fipple or mouthpiece. However, lately from the same region they found a flute even older (42,000 yr) that had an unmistakable notched mouth. I don't know about holes though, but that wouldn't mater. I need to do this demo with my harmonic flute otherwise known as the Sal of Scandinavian origin. No finger holes at all! The harmonics can be played up to double digit range with no moving parts or skill. 9,10,8,2,3? That tune from Close Encounters of the 3rd Kind. As Carl Sagan would say fundamental and valid throughout the universe. Don't leave home without it. With a piano for a demo I would just lightly finger that low C and pull all those notes clearly out of it. You would have to take the lid off though. I like to play on just 2 notes and trill on those 2 keys will spilling gobs of notes out. I remember this lecture at Purdue 1972 or so, when the prof got to the seventh harmonic he said " that one's a wild card we'll throw that one out". No brother! That's the flatted seventh of the Blues, Gospel, Bluegrass, Barbershop, and all the way back to Africa. He didn't want to get into the comma and all that equal tempered mess. The fifth is a little off but the third is really out of the ballpark, the seventh is to some magic or heaven. I am mathematically dyslexic. It took me a long time to understand that there are seven notes in an octave. We all call that 12 tone serial stuff "12 tone" yet keep saying this math myth about the diatonic scale. No wonder America's math score is low. Roman time and the 123...890 way of showing the numbers. Poor Zero he's always getting left out or last in line, instead of first.

.....and besides that, the only pitch relations one can play on the piano from the overtone series are the octaves. Every other pitch is not available in equal temperament​.

Actually not even the octave is a perfect octave on the piano, its stretch tuned so no interval on the piano is true. This should clue us in that "perfect" is not required since the piano sounds wonderful without a single justly tuned "true" interval.

[@billwesley]

Yes, the 7th partial with the 4th partial does not sound like the interval of the sixth, it sounds like a very clean m7th, if you use 7/4 (m7th) in place of 5/3 (M6th) you will not get the same result.

[@kevinpowell6281]

and that's the "cultural conditioning" part. It depends on which culture hears the harmonic. some cultures descibe it as a sixth, some cultures hit on the flat 7th.. the so called "blues" note, or the major 7th. It's a point of cultural view.

The whole premise of the pentatonic being derived from the harmonic series is surely wrong. The pentatonic is built from Pythagorean perfect fifths. The seventh harmonic is flat of the equal-tempered minor seventh by only about 3/10th of a semitone, making it sharp of the major sixth by almost 7/10ths of a semitone, so to refer to it as a sixth and part of the pentatonic scale is incorrect.

[@OfAngelsAndAnarchist]

This guy is really late to the party Nowhere near as elegant or useful an explanation as bobby mcferrrin he just sounds like another teacher bring back the master !

[@benjaminwoollard4038]

Bernstein did it

[@MarkRaymondLuce]

I think you are right - I saw that once, I will look for it; thanks for posting.

[@chrisw1462]

Overdrive must also be universal... :-( If you're talking about SOUND, you might want to be sure your own sound is set up correctly. With the voice driven into distortion, its hard to hear the much quieter piano in several places.

[@Florestan1000]

Yeah,, he is on the faculty at Juilliard .. just saying .

[@wbiro]

Amazing how the scale was constructed on harmonics (nearly)... nice Debussy, but awful arrangement of Purple Haze (standard piano tropes just don't cut it)... also the harmonic phenomenon begs the question, which came first, harmonic music or the way we sequence our tones while talking - one would think that music melody mimics talk, but it appears to be the other way around (given the underlying harmonic aspect)...

[@The22on]

Those who pressed thumbs down were Neanderthals who didn't write pentatonic scale music!

[@titanarmy4116]

so tedx doesnt mind blatant plagiarizing of Leonard Bernstein's lecture?

[@seiph80]

Titan Army that's exactly what I was thinking

[@timcox5373]

Thank you! Much of it verbatim

[@ToadInTheWoods]

Thank you, and others who have pointed it out. It is straight-up plagiarism, and it is shameful.

[@hanktheblesseddeejay]

You can't really escape the information being the same, but he could've just given the nod to LB, here he feels like he is passing it off as himself

[@The22on]

Some great people have said, "I only steal from the best". Even if it's mostly Lenny, it's good that he posted this. It makes us think.

[@ukaszk.8305]

A continuation of Bernstein's music education legacy? ;)

[@samueldegrandi4125]

hes talking about the major pentatonic right?

[@clowdzfrumubuv9354]

Yes, he is talking about the major pentatonic.

[@burntsider8457]

Higher pitch to the left? Lower pitch to the right? Huh?

[@cjhtas]

To McFadden’s left and right of course. As in he jumped to his left.

[@angelcarrillo980]

I paid for a +$100 college textbook just to be full of free, un-restricted, and unofficial sources like these. The book itself has little text for itself. Feeling ripped off today. Is that okay?

[@teddydunn3513]

This guy is just some random musician who studied at Julliard. He's not an expert on sociology or psychology.

[@samarthkumar1408]

Left?

[@MICKEYISLOWD]

He forgot John Lennon's Jealous Guy. Its wholly pentatonic.

[@walkaboutarts]

BERNSTEIN BITER!

[@MichalDirer]

i dont hear C

[@NinjaDeathTeddy]

Why don't things sound out of tune when you are playing in a minor scale if the fourth harmonic is a major third?

[@Shermanbay]

1. The major third is rather weak. 2. A conflict between the major and minor thirds is exploited in many musical genres, i.e. blues, and is expected and desirable.

[@billwesley]

The fourth harmonic is a double octave and not a major third, for example the fourth harmonic of C1 is C3. The fifth harmonic is a major third , C1 has a fifth harmonic at E3, but this is so high above the C and is usually so low in amplitude you can not hear it that well, but you are absolutely right, the minor scales sound slightly less consonant than the major scales for exactly the reason that the 5th harmonic is out of the minor key signature but is within the major key signature. This slightly greater dissonance makes minor resolutions a little less compelling and more troubling, but troubling is what minor does best anyway so this is probably a good thing.

[@vesnyakinci]

H H HOTTT!!

[@johnvarney3750]

The harmonic series doesn't exist on equal-temperament piano notes.

[@angusbrooks1077]

his scottish thing at 7:52 is the australian anthem no not land downunder :|

[@mousaey]

That's Auld Lang Syne...

[@angusbrooks1077]

ive no doubt , but it sounds like the verse part of our anthem "Our land abounds in Nature's gifts Of beauty rich and rare;"

[@gerrycoogan6544]

Be that as it may, it's still "Auld Lang Syne", a Scottish tune that's hundreds of years old. :)

[@damiangaskell8488]

@@angusbrooks1077 I'm an Aussie, and it has the wrong timing and the wrong notes to fit anywhere in our National Anthem. It's obviously "Oldangzine". I'm sorry, I just can't hear it.

[@willallenking4809]

This is not, Advance Australia, Fair... at all.

[@nenissaK]

the mic is clipping because it's too close to his mouth

[@hal7ter]

They no longer have the Bobby McFerrin piece - grrrr. Kinda leaves this guy's presentation high and dry.

[@profil4e]

Well try Bulgarian folklore, like " Pilentce pee " or " Валя Балканска - Излел е Дельо " ... there is No universal note pattern!

[@djanra3427]

that is a cheap plagiarism of Leanard Bernstein first Norton lecture...

[@philippamcintyre7995]

It's not plagiarism - it's commonly accepted knowledge which Weisman does a really nice job of explaining (without trying to claim its his discovery). The Harmonic Series (and subsequent pentatonic scale) is related to French mathematician Joseph Fourier's (1768-1830) Fourier Theorem.

[@bassmaiasa1312]

Yeah, and there's a professor over at MIT plagiarizing Isaac Newton in the calculus course. Terrible!
