Pianists must often hit keys in very quick succession. The following figure displays a typical piano keyboard.

(a) Compare the index of difficulty for striking C, C#, F, and F#. Assume one is starting from the A key and distances are measured center to center.
(b) If starting from the A key, it takes 200 msec to strike the C key, and 500 msec to strike the F key, what is the bandwidth of a typical pianist?
