this is what i found:

The standing wave frequency of any drum can be found by the formula

*f = V / 2d. V = the velocity of the sound wave which is 1130 ft/sec, where "d" is the dimension in feet and the "f" result found will equal the fundamental frequency.*

What relevance is this? The drum inherently will produce a very resonant note regardless of tuning based upon dimensional characteristics but will be extremely strong once heads and everything else allows it to be truly tuned at that frequency. So for a 24" bass drum you can find that 282 hz is the most resonant note for this size drum, which is musically right between a C#4 and D4. Whereas a 22" drum equates to 308 Hz, or musically between a D4 and D#4.

If you apply these principles to a 12" tom, you get 565 Hz or between a D5 to D#5.

the part im unsure with is the 2d, say im tuning my 13x6 snare is it 2 x 13? or 2 x 6? or 2 x 13x6?

also what didn't make sense is that it says for a 22" bass which is what i have, 308hz is the most resonant tone? thats incredibly high as so far we previously tuned to a fundamental of around 80hz, 308hz is way higher than my snare.

if someone could help me understand this that would be great!

thanks if you can help!
