Igliashon Perplextus Jones, also known as Jason Yerger and Chuckles McGee, is a guitarist and composer living in Portland, Oregon. Born in 1982 in San Mateo, California, he has been studying microtonality since 2003. He has released numerous albums of microtonal music in a wide variety of tunings, under several aliases, mostly equal divisions of the octave. He has been an active (if controversial) participant in the online xenharmonic community for many years, dating back to the Alternate Tunings Yahoo group (aka "the Tuning List"). He currently plays guitar in the 17edo progressive rock band The Mercury Tree.
Approach to xenharmonics
While Igliashon favors equal divisions of the octave, he is an enthusiast of all forms of microtonal theory, including regular temperament theory and just intonation. He subscribes to the belief that there is no single best tuning or approach to tuning, and encourages collaboration between those with diverse views and backgrounds. Igliashon is primarily a guitar player who dabbles in composition for electronic media. He currently owns guitars in 13edo, 14edo, 15edo, 17edo, 21edo, and 23edo. He has owned guitars in 16edo, 18edo, 19edo, 20edo, 22edo, and 31edo in the past, and has recorded and released music using each and every one.
As a theorist, Igliashon's main area of interest has been on JI subgroups of the 17-limit, and temperaments thereof, as applied to equal divisions of the octave below 24edo. His research has focused especially on EDOs normally considered to be too dissonant to be useful for harmonic music, such as 8edo, 10edo, 13edo, and 23edo. By applying the principles of regularly-tempered subgroup harmony, Igliashon has found consonant triads, tetrads, and pentads in all of the EDOs below 24, and has contributed much to the wiki articles on those tunings.
