Temporal resolution of the brain

As part of an investigation into how the brain records patterns of stimulii
and responses, it would help to know how accurately the brain can resolve
temporal events.

To give examples:-

1. If an experienced musician hears a piece of music, how closely can he/she 
follow the tempo of the piece when performing it some short time after 
first hearing it.

Two measures are of interest, a) the temporal error between any two points in 
the piece and b) the cumulative error over the whole piece. Might there be 
intermediate errors that are greater than the cumulative error or does 
the cumulative error generally increase over the duration of the piece?

2. If an experienced musician performs a piece of music with which he/she is 
familiar twice in succession how closely is the the tempo maintained
between the two performances using the two measures above.

I would be very grateful if anyone could give some pointers to published
research on this subject or who can otherwise shed some light on the matter.
