This morning I installed a music player that I am unfamiliar with, and decided that the first thing I should listen to is Angine de Poitrine Vol. 1 and Vol. II since I hadn’t listened to them in a while. And then I found, by coincidence that they played the Montreal Jazz Festival last Saturday (June 27th, 2026) and broke the attendance record set by Stevie Wonder in 2009.
Not true. Jacob Collier, David Fiuczynski, Matthew Garrison, and others use microtonal notes with their guitars.
Sam Nanton (Duke Ellington) also used a lot of microtones in his trombone solos.
It does happen…just not very often.
