This question already has an answer here:
I have extracted the measure in question that I'm struggling to understand how the notes line up to the existing (4 4) time signature.
As I understand, the bass has 16, 1/16th counts, but the treble portion has 35, 1/32nd counts (too many). As far as I can tell, each 3-bar set of 32nd notes on the treble portion are suppose to be 3/32 count of the measure but I'm not sure what the '3' written is meant to indicate. It feels as if the 3-bar set of 32nd notes should be 1/16 of the measure, which would then create a measure total of 32, 1/32nd counts but I'm not sure why?
I'm sure there is a musical term for this that would help point me in the right direction.
