Siren hole geometry directly determines pitch and tuned intervals.

Evidence

The temporal theory of pitch perception is based on the fact that the waveform of a sound with a strong musical pitch repeats or is periodic (see Table 3.2). An example is shown in Figure 3.1 for A4 played on four instruments. The f0 for a periodic sound can be found from a measurement of the period of a cycle of the waveform using Equation 3.1. — David Howard, Jamie Angus, coustics and Psychoacoustics, 909 (#expands, via linked claim)
