shape of closure on open-closed resonator
shape of closure on open-closed resonator
(OP)
I have an open-close relative wide resonator, 7.5? in diameter. above it, there is "a big idiophone bar". first two frequencies of this bar are tuned in interval of 12th.
also, open-closed resonator´s first two freq. are in 12th.
resonator should support bars in volume, they should resonate
so, closure must be:
-flat?
-convex?
-concave?
-shape of sinx+sin3x???
Which will support sistem better, the best?
Thanks,m

Here is a reference for resonant tubes:

A closed tube with a flat end is probably better. A loose/flexible hanging support from the tube wall is probably better than a rigid support. I am a acoustics guy with no musical instrument experience.
