I’m currently studying out of the art of bop drumming by John Riley which is a book on jazz. I’m learning to play comping exercises with the snare and bass drum and I’m still having trouble keeping consistent volumes with the bass drum feathering. I’m using heel down. Sometimes I press down on the pedal too softly so that no note comes out or sometimes I’ll hit it too hard and it doesn’t sound subtle like it should be. Is this something that just comes with time? Or is this a technique issue? With the comping of snare and bass I’m keeping the regular typical ride pattern in jazz and 2 and 4 on hi hat foot.
