12TET (12 tone equal temprament) is a system which divides the octave (eg. C3-C4) in 12 equal parts and it’s the system used on many instruments, especially in western music. Maybe I’m getting bored of it bc of the fact that I’ve probably heard every possible combination of notes in this system. The thing i hate about it is how limiting it is, because in between even a semitone there’s a world of possibilities and i wanna study and use microtones. The thing is guitars are caged in a 12 tone system, as many western instruments are. My point? I WANT A FRETLESS GUITAR/INSTRUMENT I WANNA DISCOVER MICROTONAL CHORD CHANGES bit of a rant
Im obsessed with historical tunings and temperaments. Early music sources (YouTube) has a good intro to just intonation. It’s a great intro to how the Pythagorean comma manifests if you’re interested.
In case you’re interested in the harmony/composition side, Schoenbergs book on harmony begins with a very nice derivation of the 12 note scale. Extending it to 24 should be fairly easy. So after that, developing a harmonic language becomes slightly weirder. Hindemith or Uhlela might be able to establish rules on harmony but this is the extent of my knowledge.
