This is really interesting and brings up a few questions for music education: how do we (and can we even try to?) go about teaching this? There’s the straightforward, mostly academic “instruments, important figures, significant songs and albums, swing feel, groove, blues scales, syncopation, etc. etc.” kind of approach that I’ve experienced in my own education, but is that all that it really takes to get your brain to start working in this way? For the sake of facilitating education I think it’s probably important to try and focus on this, see if the study and its results can be replicated consistently in order to see if a teaching method can be derived that can best scaffold the student towards this kind of behavior, but at the same time I feel like that’d take away a lot of the fun of playing jazz. Wouldn’t it be more serendipitous if we just arrived there accidentally-on-purpose?
