I'm a recreational drummer, practising some fills at the moment. And to get a better understanding of how the following drum fill (starting at 1:05), covering what I believe to be two measures, is played exactly, I'm trying to write it down in musical notation (in MuseScore). However, with my limited knowledge of music theory I just can't seem to figure out how it is played exactly and/or how it should be notated.
At first I thought I heard twelve 16th notes, followed by ten 8th notes (which would add up to two measures), followed by the crash on the first count of the "third" measure. But on further inspection (I've slowed that portion down in Audacity so I could hear it better) I believe I'm hearing eleven 16th notes first, followed by ten 8th notes, followed by the crash on the first count of the "third" measure. But, eleven 16th notes and ten 8th notes don't add up to two measures.
So my question basically is: what is going on in this fill, technically? Could you help me understand and help me determine how this fill would ideally be notated?
