Tip!!!
-knead the edge of a new head for two turns (until the glue dosn't krackle any more)
-only do half/quarter turns one a lug then tighten the oposit lug. Always tune crosswise.
-use a paper stripe to measure the distance from hoop to lug and make it equal on all lugs of one head. That is usualy a good starting point.
-if you need to tune the pitch down make a half turn down and than a quarter turn up, push your hand into the middle of the head three times and go one! (like on a guitar/bass only tune up to a pitch).
-put the drum on the ground for tuning.
-start with the resonant heads (the tighter they are the shorter the sustain).
-batter heads should be in tune with the resonant heads or lower.
