Drum Tuning
The idea is to keep the tension as even as possible around the head, much like tightening the lug nuts when changing a wheel on a car.1. Before mounting the head, check the bearing edge for roughness or bumps. It should be smooth to the touch. Look across it from one side. It should be uniform in height. If not, consult a MASTER woodworker.2. Lay the head on the shell, mount the rim, and screw each tension rod in finger-tight. With a drum key, tighten each rod one full turn (360 degrees).3. If you're using an old head OR a Kevlar head, skip to step 4. Set your drum on the floor (on carpet to protect the bottom of the the shell) and stand on the head. If you're a heavy person or if the head or shell is very delicate, just sit on the head. Now bounce up and down *slightly* for a couple minutes. You'll hear cracks and pops as you "seat" the head onto your bearing edge and as the resin used to hold the head into its bead cracks into shape. Slam the edge of your fist into the head about 20 times. This will pre-stretch the head so it won't go out of tune as quickly at first.4. Tighten each rod about another full turn. Most of the wrinkles should be gone at this point. If not, tighten each rod a quarter turn until the head is smooth. The head should now produce some sort of tone when struck.5. Tap the head at the edge beside each lug. If the pitch is slightly lower at one lug, tighten that rod until it matches the two points next to it. Repeat until the same pitch is heard all the way around the head. Getting the head IN TUNE now will make it easier to tune when you finally tighten it up to the desired pitch.6. Tighten each lug a quarter turn and check the overall pitch. Repeat until the desired pitch is found.7. One last time, tap around the edge and fix any inconsistencies in the tuning of the head.8. If you use double headed drums, repeat with the bottom head.
