Nine-Tone Studio

An equal division of the octave into nine parts — 133.33 cents a step — after the system Francisco Mora Catlett set down in 1997 and the frequency tables Dale Joachim computed at Michigan State the same year.

Five white keys, four black. Reference A = 450 Hz. Three of the twelve familiar pitches are gone; three remain exactly where they were.
