Capture the keys you play, or type a short phrase from your own notes. Each captured note starts at 1 beat. Use E:2 for a held key and _ for a rest. Touch-only notes use Western names, such as C6:2. Up to 48 notes per phrase.

Your notes stay on this device. Copying a phrase link includes those notes for its recipient.

A gentle first round

Keep the drone low. Match one note before adding speed.

Today’s target

Three clean repetitions are better than one rushed run.

How to use the drone

  1. Choose the Western pitch you use as Sa.
  2. Start with Sa–Pa. Choose Sa–Ma when the raga or lesson calls for it.
  3. Keep the drone quiet enough that you can still hear the centre of your own note.
  4. Hold Sa, release it, listen again, and repeat before adding a scale.

Tanpura-inspired vs shruti-box tone

The Tanpura-inspired option has a slower, moving texture; the shruti-box option is steadier and more reed-like. Both are synthesized in the browser and are intended as simple pitch references, not sampled replacements for an acoustic instrument.
