I’m surprised to have found a video clip of a lesson, by the great jazz/fusion guitarist Al Di Meola, with an open HBD-related aside.
You have to scroll to around minute 2:35 to hear the comment in its context. In short, Al Di Meola states that Asians and European Caucasians are unlikely to be able to play against the time. Playing against the time involves one keeping a basic beat, without the aid of a metronome or other device, and being able to play radically different rhythms without swaying from that beat.
I follow a lot of guitar playing, and what Di Meola says seems to be true. Do you think it is true? And if so, what could be a potential HBD basis for it?
