there are alot of ways to tune drums properly to get the sounds you want, and all those variations are good. It is still ultimately about feel but so many guys, especially young ones, are just completely clueless or don't tune them at all.
I backline/teched for Kenny Washington on a gig. He was a very cool guy and while we were changeing heads he was talking about tuning, it was amazing, he was tuning top heads and bottom heads, and listening to how it affected the WHOLE kit. The resonance of each drum affects all the other drums. I wish more drummers could do this, it is, after all a musical instrument.
