Manual Pressure Mode

Use the slider to set a fixed bellows pressure. Great for keyboard playing — set it to ~75% and focus on the keys!

Camera Pressure Mode

Wave your hand in front of the camera to pump the bellows. More motion = more volume — just like a real harmonium!

Playing Technique

Hold a key for sustained notes. Release quickly for staccato. In camera mode, move your hand steadily for smooth sound.

Octave Choice

Octave 2 (Q–U) is the sweet-spot for melodies. Oct 1 = bass, Oct 3 = treble. Most songs work best in Oct 2.

Sargam System

Sa Re Ga Ma Pa Dha Ni = Do Re Mi Fa Sol La Ti. Sa is C — the natural scale uses only white keys!
