A lot of classical composers, wrote oddball figures per beat. Bach and especially, Giulianni. G is real special about writing impromptu sections. Advanced players read and play this music like a walk in the park. You just can't walk through the park on the computer. Try taking an impromtu section of a classical guitar piece and write it within a computer and then have the computer play it correctly. One learns an awful lot about time and people's and even your own perception of it.
