I find it rather interesting that since I've been recording MIDI 
keyboard input to sequencers - I have to turn on a metronome and really 
really really concentrate to make notes land on the allotted beat. Left 
to my own, my rhythms change, what I might have heard (while playing) as 
4 8th notes was actually 5 8ths played in the same amount of time, etc.

My classical piano teacher once told me that I had a natural syncopation 
to my playing. Took much work to get that under control for classical music!

Then I learned a Chopin composition, and my teacher told me that in some 
passages the only time it was important for both hands to be in time 
together was that they both reached the end at the same time. ;-)
