Drone Center

A continuous C+G drone holds the key. The app plays each target note briefly — then you sing it back and sustain it against the drone for 5 seconds.

How a round works
  1. 1. The drone hums underneath you throughout the whole session.
  2. 2. The app plays the target pitch on top of it for ~1.5s.
  3. 3. Then it goes quiet and you sing that pitch — sustain it for 5 seconds while the live meter shows how close you are.
  4. 4. You cycle through 5 targets: tonic, 5th, 4th, 3rd, octave.
