Groundfault
Sky Talbott-Settle, also known by her online alias groundfault (aka ground), is a xenharmonic composer, music theorist and co-host of the podcast Xendergarten living in Madison, Wisconsin. She has contributed the following innovations to xen theory:
- Aberrismic theory, a theory of scales obtained by taking a given melodic scale pattern and adding steps (smaller than the existing steps) approximately 20 to 60 cents in size, called aberrisma steps. Diasem (5L2m2s), blackdye (5L2m3s), and diaslen (5L2m4s) are some scales that result from the diatonic MOS via this operation. Aberrismic scales are groundfault's principal way of using edos > 20.
- Zeta peak integer edos, the pure-octave constrained counterpart to zeta peak edos.
- Several temperaments, including Flutterpyth, Pentagoth, Tragicomical, and Dirt.
Approach to xenharmonics
groundfault mainly uses aberrismic theory by mapping JI scales via edo vals to equal temperaments. She always works in full edos and has released music in 11edo, 16edo, 20edo, 25edo, 27edo, 29edo, 31edo, and 32edo (often combining edos).
