| One vent hole would be used for one note and the other vent hole for the other another note ... if thats a picc... im not sure which notes they would be used for. However, due to the physics, each note has a sweet spot where the vent hole should be drilled for it to function properly and sound correct.
These things are a headache, when I was studying on Rotary, the horn i borrowed had 3 of these things... but they make things speak so easily, so its totally worth the hassle to learn to use em.
