I have trouble keeping the tempo steady while playing in my school's jazz band. Of the 15+ people in the group, the only ones who seem to have any sense of time and actually try to keep the tempo steady are me and the lead trombone player. The drummers just don't do a good job, they're always rushing and dragging, never steady at all. Sometimes I find that if I'm not 100% focused on tempo (which i shouldn't have to be) I'll just follow the drummes at whatever tempo he speeds up to/slow down to. I know practicing with a metronome helps, but that doesn't do much when everyone's got their own tempos. I realize it's important to "lock in" with a drummer, but what do I do in this situation? Should I just completely ignore what I'm hearing from everyone else and stick to what the conductor gives as a starting tempo? Play harder on beats 2 and 4 so everyone can hear?
