I once clocked some banjo players, both clawhammer and bluegrass. The fastest was about 349 beats/minute which is almost 700 individual notes. That's almost 12 notes per second, which, in animator-speak, is 2 frames per note.
At that speed, most of the notes are not exactly meanful, more just rhythm.

(I note that prestissimo is usually defined as anything more than 200 bpm)
