Hi all - jazz drummer here. What @bdp24 wrote is spot on. In a jazz combo, I almost never keep time with the 18" bass drum; it serves as an accent piece while my hi-hat is the most metronomic instrument, followed closely by my ride. When I do emphasize the bass drum, it’s on a powerful punch accent but that’s about all.
Now, in my modern country project, the 22" bass drum is where it’s at!
