from Greek -"Arithmos" (number), and "Tonos" (tone). I have been practising arithmotonality since 2013 after reading Harry Partch's Genesis Of A Music and studying just intonation at UDK Berlin. Arithmotonality includes just intonation as well as tempered tunings and chaotic intonation. It is not microtonality because it does not see 12-Tone-Equal-Temperament or any tonal system as an important point of reference. For the same reason, the term Xenharmonics cannot be used for my approach, either.
