Jazz Pianists Show Higher Flexibility in Planning Harmonies when Playing the Piano (image) Max Planck Institute for Human Cognitive and Brain Sciences Share Print E-Mail Caption 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 planning.
