On drums...

I thought we called it dead, or solid, or deep... good though!

I'd be interested, but I don't think my technique would help at all in this experiment..

Check out the entire website. This guy makes patterns of all sorts of things, but relevant and interesting bit of reading w/ visualizations here:

A few items that seem obvious, but should be mentioned just the same;

The less damping the batter head, the more the harmonics, and the greater the differential between center and off-center.

As damping on the batter head decreases, tuning becomes more critical. To get a good (to me) tone from two open single-ply heads, the tuning needs to be identical. "Just above wrinkle" works great for rock with dampened heads, but with two open heads it sounds as if the drum were falling apart. (Can we state that the thinner the membrane, the more articulate it becomes - including all sorts of stuff you don't want to hear?)

Volume can be increased by lessening damping (if that doesn't seem obvious, then you have brain dysfunction much like mine).

Cliff, how far off the floor is the beater axle of your Cobra?

What if we did all have the same opinions?

Thanks for that measurement, which is the same as the Signature pedal. I would think it difficult to get much lower and still have enough pedal movement, at least in the standard arrangement.

I look forward to hearing your take on the wave form page. I can't quite figure out how all those different forms are created, other than 0,1 and 1,1.

Greg,

Checked out the wave page! What great info.

Like you; however, I'm confounded on anything past modes (0,1) and (1,1)!? I have a friend who dabbles in physics so I'm planning to run it by him this weekend and get his take.

Also, the author of this link keeps referring to a Timpani's tone which, from any that I've seen/played, have only one head and a hollow, bowl-like hull. Do you think that two-headed drums will produce different results as there are two heads set into vibration vs. one?

Dunno. According to this guy, all drums act the same, though surely the other end will have an effect on rebound. Others have suggested that tymps are alone in this respect, but check out this page from the same site that gives an understanding of monopole, dipole, and quadrupole sound array that helps explain "effective radiation."
