Harmonic series as a giant piano arpeggio
HTML-код
- Опубликовано: 15 окт 2022
- Twenty up-and-down arpeggios, each adding an additional note from the harmonic series.
You might notice the notes aren't all "in tune" with a normal piano. The numbers after each note represent the pitch change in cents, e.g. F# -49 is about halfway between F and F#. (Read up on different temperament/tuning systems to get an idea of why this matters...I'm too lazy to explain it)
Musically this isn't a very meaningful experiment, but I thought I'd do it anyway!

It’s pretty incredible how if you play any one of these notes by itself, it just sounds like a single note. But if you play any particular combination of notes, the harmonic frequencies multiplex to create a convoluting effect which results in your mom
Wow
Wow
well said
That's music theory for ya
Couldn't have said it better
That went from extremely peaceful to kinda scary
My dude it was scary since second 2
I'm a big fan of nature so the whole thing was beautiful
I wonder how this would sound if you used sine waves as the piano sound since some of the modulating "out of tune" sound is probably caused by the piano soundfont's overtones
No i don't think that's the reason.
The reason should be the following:
given a base frequency of 100Hz for example, harmonics are frequences multiple of that, so 100, 200, 300, 400, 500,...
Now think about for example 300 / 200 = 1.5, which is the PYTHAGOREAN ratio of the fifth.
The problem is that our temperament (the tuning we use) is NOT the pythagorean one (exactly because of these odd sounding notes in the video), but the EQUAL one, in which frequences are in IRRATIONAL ratios (the ratio between the frequency of a note and the one 1 semitone below is the twelfth root of 2).
So Im pretty sure this sounds awful for this reason, I hope I explained myself im italian, btw if you wanna know more about temperaments I can tell you maybe not via YT comment 😂
@@marcellomarianetti1770 I agree, some of it is probably due to the temperament. Pythagorean tuning isn't gonna work much better in this video's arpeggio example though because the sheet music is also rounding many of the closer ratios (higher frequencies) into semitones, and Pythagorean tuning has a pretty big comma for semitones
Pure sines would probably sound harsher. Check this experiment I made some years ago with 4 sines in just intonation. Interactions between sines feel like they cancel or add to each other to much, like microtimes with no sound and microtimes with too much sound, I think overtones aliviates this feeling a bit because interactions tends to result in sound more times. Just some mental notes I had, hope it makes sense. ruclips.net/video/AI3f7B3PYZk/видео.html
@@nicholasz2510bro if u listen right u can hear the Bb sounds super flat... perhaps like 31 or so cents flat. Its not 12EDO its obviously tuned to be close to pythagoras
@@thiagogomes3226 Thank you for linking that!
idk why but i hear this as an opening to an epic piano concerto 😅
Rachmaninoff could have done it, hahaha
Try Busoni's Piano Concerto, when the piano enters in the first movement
Ravel’s left hand concerto has a section at the beginning that sounds like the beginning of this video.
No
The forbidden Mahler piano concerto
2x sounds like a helicopter blade slowly spinning
Thanks for the suggestion to listen at different speeds. .5 was scary.
.25 speed at the end sounds like a sound effect they would use for a UFO hovering or something in an old science fiction movie
1.5x sounds like a lawnmower starting
For some reason the comments on this video got deleted. Not sure why. Sorry!
Starts to kinda sound like the Tardis at the end.
Very cool!
Divine!
The higher they go, the less I want them.
It's so dissonant but actually stable(for obvious reasons)
F#-49, G+2, and AB+41 sound like an emergency alarm
Technically the 11th harmonic F# is actually closer to a microtonal F‡ (half sharp)
technically most of the notes are wrong 💀
Not exactly 551.3179423648 cents is not equal to 550 cents
@@fagclownet I see you are a mathematician
@@inanis9801 I would rather say a musician who knows how to measure intervals ;)
"technically" the 11th harmonic is not an exact F half-sharp
Thank you so much for uploading this! So helpful!
How does the gap go from where this ends to the next G?
omg i love how hell sounds like
Aka the sound of me fucking around with an autoharp in the used music store
Something to play with
WOW
Sad you had to stop there, it was just about to go interesting... 😅
Tbh I might make another one soon. If I can figure out how to write scripts/code in MuseScore (so i'm not manually changing every note) then there's no limit to how far it can go!
@@brycehm There are music generation libraries out there like music21 for python, and others. This specific project might require a bit of math/logic boilerplate though
Something is comfortinh about the 13.
How about the pure tone?
It's fascinating how everything in the universe seems to have this weird tendency toward imperfection, as if infinity itself admonished our longing for grasping it. You can see it everywhere. In this quaint demonstration it feels like the upper tones of the overtone spectrum try to overcome their containment, but the skin layer that lies between here and infinity breaks the harmonics and makes the futility of triyng to escape from this contained world audible.
Imperfection is subjective, not like "ohh nothing is perfect we are all imperfect children of mother earth" but just remember when you say everything tends towards imperfections, you're not an objective observer of what's perfect. Your cat probably doesn't care about music that humans like. You create your definition of perfect yourself when it comes to subjective things like music taste
@@LevantWasTaken imperfection not in that sense, more in the sense of being confined. A circle is perfect in some sense, yet when you look at Pi it's an seemingly orderless endless string of numbers. Imperfection in the sense that there's no perfect tree anywhere, but only individual specimen. What I think I'm actually referring to is the idea of a world (not the earth, rather the cosmos, all that is) as a densification of limitless potential into a form (a specific form), whereas perfection can only exist in an unbound limitless dimension.
it's the 12 tone equal temperament that is imperfect not the natural harmonics
I think you guys are missing his/her point
What nonsense
even its shape in the staff reveals the pattern
Robert Rich begins some of his tunes sort of like this, with a harmonic sweep (Neurogenesis): ruclips.net/video/H9Nq69IkMKo/видео.html He uses just intonation. (Electric Ladder) ruclips.net/video/i55xPM_h6GM/видео.html
Bb -31 where it's at
I enjoyed that! Bryce Messiaen?
Lol half the effect is j that you’re shoving more notes into the same space so it gets faster. I feel like keeping a steadier tempo could show the real harmony better
is this Sibelius? Can you program it to play notes at specific HZ ? I have final :(((
This was Musescore! I did it manually, by clicking each note and changing the "Tuning"
If you want to use code....maybe save the file as a .mscx (not .mscz) and use Python to modify the values. There's probably a better way but that's how I'd do it
@@brycehm Wow I didn’t know musescore could do that! Never used it. Thank you! Definitely not trying to learn python haha
This sounds like Gilla Band's guitar player
this is what I will play for the aliens when they arrive, thank you, let the composing begin!
Typical liszt piece:
0:20 freedom dive
E-14 🤨
why did you stop???
lizt be like
Where are my microtones?
Subharmonic when
sounds like an elephant
F#-49 effed it up it was ok up until that.
Next time you get really p*ssed at someone tell them to "go F#-49 themselves" and they'll C how much you and them are in different vibes
this is what an anxiety attack sounds like
And THAT my friends is why harmony isn't arbitrary or contrived. Chord of nature dictates it.
I sort of agree, but then saying Chord of Nature and then the final chord sounds like absolute garbled trash is kind of funny
@Andrew Dodson Good point! Time for recycling? Fallen leaves making an apparent mess...
Oh so you too think that any music other than works by Grisey & Murail are decadent?
@@arielorthmann4061 No, I imagine that's what you're saying.
Sounded like “dry helium”
Cthulhu's entrance music 👾
too muddy
So basically a glissando on a piano out of tune...
Fake where are the microtones. A piano is out of tune
Dude, the video LITERALLY SAYS that it uses microtones. This is effectively in 1200tet, being tuned to the nearest cent
E-14 🤨
Hey I’m back. Hello me.
