More Details

The first 5 buttons (A and the C-buttons) are called the "blow" keys, or note-producing keys. Pressing one of these buttons causes the ocarina to sound.

Generally, the ocarina will only sound if one of the blow keys plus zero or one of Z and R (the shift/accidental keys) are pressed down. Pressing more than 1 blow key, or pressing just Z or R, will not result in a note.

Using the default configuration it is possible to sound any note from B, (the note below middle C) all the way to F', resulting in a range of about one and a half octaves. However, the configuration is such that without pitch bend (joystick up/down) it is impossible to play G, a common note.
