Vindication! Knew I wasn’t nuts. “Keith Jarret, world-famous jazz pianist, once answered in an interview when asked if he would ever be interested in doing a concert where he would play both jazz and classical music: “No, that’s hilarious. […] It’s like a chosen practically impossible thing […] It’s [because of] the circuitry. Your system demands different circuitry for either of those two things.“ Where non-specialists tend to think that it should not be too challenging for a professional musician to switch between styles of music, such as jazz and classical, it is actually not as easy as one would assume, even for people with decades of experience.” https://www.cbs.mpg.de/brains-of-jazz-and-classical-pianists-work-differently

When the scientists asked the pianists to play a harmonically unexpected chord within a standard chord progression, the jazz pianists’ brains started to replan the actions faster than those of the classical pianists. This was measured by EEG  (Electroencephalography) sensors on the back of the head, which detected the brain signals in the related brain regions responsible for action planing. © MPI CBS
