undercutting the holes does actually modify the tone dramatically. For a Helmholtz resonator it is not only the open area which counts, but also the length of the windway. Apart from the blow hole any open finger-hole acts as a windway and its length matters.

Hi Caran,

Thanks for the head's up! I'll modify my description accordingly.

Anyway, I don't think the original is actually tuned. You may try my version of a xun instead, which is properly tuned.
