To the 5 #microtonal #xenharmonic #music fans, "harmony" is not a real thing to anyone not trained to care about it & nobody can tell your 31EDO isn't secretly 16EDO(or 32/30...or a lot of things really).
However, you can tell this is 0EDO 🙃

Here's a weird one for those of you into #microtonal music (or #xenharmonic music if you're a *real* nerd). It's Ganymede by Sevish.

#GenreOfTheWeek #drumandbass #dnb

This track is well groovy, and it's in a non-octave tuning called Bohlen-Pierce. An acquired taste for some, but it works for me :)

I retuned my cello such that the strings are harmonics 2..5 of the fundamental frequency 33hz and it sounds bloody magical. The instrument rings in a way I've never felt before, the range remains expressive and the lowest string is still (approximately) C2 so (re)mapping isn't massively difficult.

The standard tuning of perfect fifths between the strings never felt completely right; the lowest and second lowest string sounded good together but the other ones felt.. overrated. For some reason I often prefer both 4/3 and 5/4 to 3/2 (the perfect fifth).

Now I'm compelled to conclude that ratios between two frequencies alone carries less weight than their relationship to a common fundamental when attempting to quantify their perceived consonance.

I need to say that I don't actually know if "relativistic tonality" is a thing. I'm intrigued by the concept and possibility of such music but, from my cursory searches and explorations, I haven't found anything that explicitly describes or practices such a style or tuning system (at least not in terms I understand). The closest would be microtonal "isomorphic keyboards" that automatically adjusts tuning on the fly to improve consonance between notes being played, but that's not quite the full point.

If anyone does know of such music or some precise terminology which describes it, I would be very interested to know.

Semi-random juxtaposition of image and music. For #fungifriday an image of #fungi encountered at Great Woods Conservation Area, Mansfield, MA, USA 1/22/2023. And here is a #freeimprovisation I made last March using an approach to #microtonal or #xenharmonic music where instead of a completely new tuning, I play mostly in 12EDO plus one special "outside" note that is showcased, here my G string tuned down a bit more than a quarter tone. #tuning #guitar #fingerstyle https://www.youtube.com/watch?v=6TAG0m44bUQ

What a brilliant idea for an album! As a musical mathematician, I appreciate this a lot.

Now in the mixing/tweaking stage of a weird and slow electronic piece in 22-EDO. Will probably release it sometime this weekend #xenharmonic #ElectronicMusic

I've been using this compositional technique for years, but I just gave it a name: a "double sieve".

I'm posting an example in 53 equal temperament (extended Pythagorean):

First, I selected every multiple of 53/31 rounded to the nearest whole and named them.

Then I did the same with every multiple of 53/22 (the Hebrew letters have to do with my Third Symphony).

(Secor's 31 and 41-tone miracle tunings are sieves of 72-tone.)

The 45th movement of my Second Symphony, "Nevada". A short example of 31-tone serialism.

Recorded with Garritan Personal Orchestra 5.

#microtonal #xenharmonic #symphonic #StringQuartet

This is how I came up with the modified Partch-Secor 72-edo subset that I use more often than anything else:

I selected all multiples of 72/41 rounded to the nearest whole. Then using all the multiples of 72/31, again rounded, I assigned the 31 pitch classes used in 31 equal temperament and 1/4-comma meantone. (Some are assigned to two pitches to avoid wolf fifths.)

I also have a 53-tone set in 19 tone classes; I'll explain it later.

Since I use 72 equal divisions of an octave (edo) in most of my music, I've proposed a logarithmic unit of measurement as an alternative to the cent: the degree, the unit used to measure angles.

That divides the 72-tone step (called a "comma" or "morion") into 5 degrees instead of 16.667 cents.

As you can see, the first 11 harmonics don't stray far from a 72-tone step, making this such a good tuning for 11-limit JI that's also a multiple of 12.

My modified Partch scale, adjusted to be closer to 41 equal temperament (11/10 and 20/11 are included even though they don't fit in the 41-tone system), displayed within an octave of a "pitch spiral". (I have to make my graphs a work of art, of sorts.)

The colors of the ratios and their places on the spiral are coded by highest prime: black 3, red 5, blue 7, green 11.

Each line radiating from the center of the graph represents a quarter tone.

In that song (still lyricless) that I posted the other day, I have a vi-V7-i chord progression. I'm in the key of A minor, so the chords are Fm, E7 and Am.

The first chord contains an A flat and the second a G sharp.

In 12-tone equal temperament, these are the same pitch, but in just intonation (or in its 72 equal approximation which you can hear in the posted video, the G sharp is actually a quarter tone flat of A flat.

First of all, in case you're meaning to ask: who the hell is Harry Partch?

Here's an old BBC documentary on American #experimental composer/ #music theorist/instrument inventor/cult leader Harry Partch (1901–1974), who invented a 43-tone non-equal tempered scale that I keep talking about.

Currently listening to this for the third time...

#xenharmonic

This is a rather boring chart. It's of all the frequencies of 72 equal temperament between C–1 and G9 (the range of MIDI). I also included the approximated 43-tone 11-limit #JustIntonation scale in the chart (my modification of Harry Partch's 43-tone scale--I'll explain that later).

A4 is tuned to the standard 440 Hz.

In the West, we use 12 equal divisions of the octave.

We should be using 31. Or at least 19. Or one or the other.

And now that we have synths and synth apps and DAWs that can run synth apps, it's far easier to do #microtonal music than it was in the Renaissance. (Imagine 31-et jazz harmony and 31-tone serialism. I've done both.)

Greetings! Here’s my #introduction
I'm here because I’m a big fan of #indiegames #ttrpgs
( @epidiah pointed me here. Thank you!)
Also “classically trained” #musician who plays #trombone and #ukulele and I really like weird experimental and #xenharmonic #music , but I’ll listen to just about anything. I’ve been a Band Director in public schools for a long time. Orchestras and wind bands should play more music by BIPOC composers. There’s no good excuse not to. #experimentalmusic #ttrpg #blm
