A double ocarina is two ocarinas sharing one body, each with its own windway. This chart is for the common Asian-system double in Alto C, the layout STL uses and most Taiwanese makers follow. Between its two chambers it covers a little over two octaves, from the low A to the C more than two octaves above. That is a fifth higher than a 12-hole can reach.

Chamber 1 is played almost exactly like a 12-hole ocarina without the right thumb hole. The low notes, the subholes and the natural scale are the same, so if you already play a 12-hole you know most of it. It runs from the low A up to D sharp, which is played with every chamber 1 hole open.
Chamber 2 takes over at E. Its holes sit in their own row under your right hand, and you move your lips to its windway, which sits next to the first. It works like the right hand of a 12-hole: cover all five holes for E, then open them from the pinky upward to climb to the top C. For the B, open the large half of the split index hole and keep the small half covered.
The hardest part is the change between chambers, because you move your lips and your right hand at the same moment. Practise slow D to E and E to D slurs until the switch is clean.
These tabs go above a 12-hole's top F as written. A C double plays them at that pitch; on a C 12-hole they have to move down.
