This is a reharmonization of Happy Birthday, tuned to 22 equal divisions of the octave. It is loosely centered around what we call "porcupine temperament."


Happy Birthday

I recorded this a while ago, have no idea what it's from

Sunset

This is a comma pump in the unnamed 17496/16807 temperament, tuned to 34-equal. The basic root movement is by 7/6, and the chords are tuned to 7-limit subminor 7 chords, to make the voice leading smoother.

This is an early microtonal improvisation of mine, which I did before I knew anything about regular temperaments. 24-EDO is the tuning, and this composition can be loosely thought of as being structured around "semaphore" temperament within it, and perhaps "neutral" as well.

Oblique Motion

This is a comma pump in porcupine which goes up by three 6/5's and then down two 4/3's back to 1/1. I designed it as an example of something that I thought sounded perfectly "natural," but which doesn't work at all in 12-EDO. I'll use this in a piece somewhere down the road.

The tuning here is 23-EDO, which does a much poorer job in approximating the harmonic series when compared to the other tunings listed here, so the chords don't seem to blend as well. That notwithstanding, it still has a certain interesting color to it, which I somewhat enjoy.

A Porcupine Comma Pump - 23-EDO version

This is mostly goofy experimental music theory stuff to see how different microtonal scales sound - no real musical compositions here (yet)
