It never ceases to amaze me. Some of the vocal cues people use to tune their drums. And a lot of times, they even sound pretty good! Perfect example of not needing to know much about intervals to get a good sound from your drums. As long as you have some sort of relative guide, you'll be fine more often than not. Tuning tenors is prolly the easiest thing in the line to tune, really. I actually have a harder time with snare drums!

i like cranking the shot and then getting drum 1 within an octave of the shot. then i'll go to a 1.5 step interval between 1 and 2, a 2 step interval to 3, and a 2 step interval to 4. for sextets, i like using the same tuning but tuning the 2nd shot 3 steps lower than the 1st shot. my preferences. these tunings are musical and high enough, that when used right, it sounds tight (clean). but also low enough where it doesn't sound brattish and you get some nice scv-esque "lowvertones".

Tune the tenors to the bass drums tunning, Old school style =D
