My primary band is a jazz quartet, and we play at a supper club once a week. When we start people are still eating dinner 10 feet from the band. So we need to play softly enough so they can still enjoy their candle lit romantic dinner and bottle of wine.
I can watch peoples faces and tell if the volume is good. If they are having a conversation without leaning in or talking into each others ears, then were good.
I use mostly brushes at first but then sticks, no special muffling, no special heads, my bass drum is wide open, just regal tip jazz sticks, but I have been playing for a while.
I understand some of your drummers are less experienced, and I guess that's the idea.
So I guess I'm just rambling. Too much coffee this morning.
Interesting to see that most people suggest that drummers need to know how to control their volume.
