how do you come up with the correct pitch for each drum? basically i have been working the head until the sound "comes together". im new to REALLY tuning drums and would like to get better. ive read all the basics of tuning. when i finish with a head, they tend to [what i think] be pretty tight and high pitched for the sizes. [13x12/14x13/16x16 toms and 14x4 snare, 22x16 kick] are there specific notes i should be tuning them to? does the depth of the shell [wavelength] determine the note? any sort of tips or suggestions would help alot. has anyone used those drum watches that measure head tension, do they help?
