Thanks David - please do report back if you do this experiment. My impression is that the helmholtz model doesn't apply very well; i originally kept the hole cut-out from my cajon with the idea that i would incorporate it as a "slide" over the hole, allowing me to vary the effective hole size and thus the kick pitch. In practice, it made no difference in the pitch (like, at all). In other words, i'm not sure there is really any resonance or vibration happening with the tapa; it seems like it is more of a "thud" wavefront. Perhaps with tapas of other sorts this would be different. Perhaps a tube would have a more dramatic influence. I'm curious too, so i look forward to anything you come up with. Thanks!
