The section "Grooving with a Drummer," Pfieffer talks about the parts of the drum kit.
The bass drum is played on the first beat of the measure. That's a downbeat, right? He suggests that the bassist match the rhythm.
The snare is played on beats two and four. He calls those the backbeats. I thought that those were downbeats, too. He suggests that the bassist play with or against the snare.
The hi-hat is played between the beats, either on eighth or sixteenth notes. Or the drummer can use cymbals instead. He says that most of the bassists notes are in sync with the hi-hat.
I got confused between the snare and hi-hat. I thought that downbeats were 1,2,3,4 (assuming 4/4 time) and that upbeats were between them (1 and 2 and 3 and 4 and). I've never contemplated the difference between a downbeat and a backbeat.
I've spent the last few days listening to songs and trying to hear the relation between bass and drum that he mentions. I figured Led Zeppelin or Pink Floyd would be good to listen to. Good bass, but my attention wanders with them because there's too much going on.
So, I put on some country. Charley Pride, Alan Jackson, David Coe. Simple enough that I can hear the bass following the drums. But I still don't hear the connection with the hi-hats or cymbals or how the drummer is signalling a change or turnaround for the music.
Hope that reduces the confusion as to what I'm confused about.
