- Just a normal ninth.
About the music: This is a piece in “Just Intonation” and you might call it “Spectralism”. over time I’m planning on covering a lot of stuff about that and microtonality in general but in the meantime, why not check out these resources:

My favorite interval al well. Specially when there's a 3/2 in between. Yes, simple and trite but I love it.
this would probably one of the first videos i'd show to someone new to microtonality
looks approachable and sounds really pretty
Sounds like random noise
Theres something so beautiful about that 9/4 cents div by 4. Is there a system behind the amount of notes you beam together?
it's enchanting
Sounds like stacked M7 chords (repeating at the natural 9th) which is always an amazing sound
ah shoot i actually did a version where i fixed the beaming to make it more logical and then didnt upload it. this is the old version, so no there is no system! embarrassing
@@mannfishh oh mann.. don't feel bad about it!
Generally it's called Mohajira - it's when you split a perfect fifth into two neutral thirds, and thus a major ninth into four. The result is very similar to the Arabic Rast scale (stacking these neutral thirds repeatedly yields Rast with a half-sharp fourth degree instead of the perfect fourth).
Sounds great!
another mannfishh banger!
How do you even begin learning microtonal theory and whatnot
Just listen to a middle school band
What a beauty!
magical!
beautiful!
oh my god the notes sound so good together. what tools are you using for this sound?
Can you do a video about 7/4? That's my personal favorite
Yes its nice
what program do you use to compose/notate these?
dorico!
pianoteq for playback (usually, sometimes halion)
6 cent split almost sounds like 5-TET.
Yeye
wow
0:38 is very 5edo-ish
yeah sounds like it
what does "9/4" mean? i'm very well versed in 12 edo theory but whenever i find myself looking up things about microtonal theory/harmony i find things like that which i can't find an explanation for. similar to "16:21:26:31:36"? can someone explain the meaning of these? thx!
The 9th harmonic with the 4th harmonic
The latter is just the hertz frequency ratios much like a 3:4:5 polyrhythm
just intonation is characterized through the use of whole number ratios multiplied with a frequency to represent intervals, as opposed to composing with equal divisions of an octave. "9:4" means (
@dnaroseandthewolves states) the interval between the 9th harmonic (9x of a fundamental frequency) and the 4th harmonic (4x of the same fundamental frequency), which forms a pythagorean ninth. it's called "pythagorean" in reference to pythagorean tuning, which constructs musical intervals by using only octaves (2:1) and perfect fifths (3:2). consequently it can also be thought as two perfect fifths (3/2 of the fundamental) stacked on top of each other, because 3/2 * 3/2 = 9/4.
it's roughly equivalent to the major 9th in 12-EDO from C4 to D5 for example, but the frequencies between the two pitches are exact rational multiples of an implied fundamental frequency, as opposed to a multiple of the 12th root of 2 raised to some power (which is always an irrational quantity except when the interval in question is an octave).
"16:21:26:31:36" is a pentachord (or pentad) consisting of the 16th, 21st, 26th, 31st and 36th harmonics relative to some implied fundamental.
How did you approach the rhythm? Does it have something to do with the tuning?
in this case the durations dont have anything to do with the tuning (sometimes they do! but not here) but the patterns are naturally dependent on how many divisions of the interval in each "cell". other than that its by 'feel'. hopefully that makes some sense.
wow this is interesting but the word " *frequency* split" confused me, wouldn't " *ratio* split" make more sense? 😅
"Ratio" wouldn't disambiguate as clearly between "cent" and "(frequency) ratio" because cents are logarithmic ratios.
What frustrates me is that I never know how to feel about microtonal music. This sounds cool as fuck, but I don't know how what emotion I'm supposed to feel!!!
one way to listen to music like this, and a lot of more abstract music, is to listen to it as a mass of sound and pay attention to how that mass changes. its true that that isnt necessarily a directly or specifically emotional experience! though you might be surprised at the way emotion can creep into it
To me it sounds surreal but in a disturbing way. Like a bad dream where you feel a sense of impending doom or something like that.
If you're from the Occident and it's not diatonic 12TET, then it's some shade of creepy.

The emotions that our society has words and labels for do not encompass the full range of human expressive experience, and music that deviates from what you’ve experienced will not fit neatly into said emotional categories. Try to take it for what it is rather than trying to break it down into a specific mood (joyful, aggregated, triumphant, romantic etc) and pay attention to raw feelings it invokes for you.
I 😍 random noise
I 🤮 classical music
