Will read through this in detail in the morning- half asleep right now. In a real life ocarina you actually do want some amount of overtones, as a pure sine sounds verry sterile and is extreamly difficult to blend with other instruments, the slightest pitch error is really obvious. Asian...

Yes, I know Jack and have seen that paper before. Looking through it I can see some issues with the models the author used for the simulations. Fir instance the following model has a substantal curve-in below the voicing which I've known for a long time to cause overtone issues. Also the defined...

I'm a maker of concert-tuned transverse ocarinas, which are a kind of Helmholtz resonator, however that does not tell the whole story as they are driven with an air-reed. This set up seems to differ from what is defined by the Helmholtz resonator equation in that it does not have a single...
