An online tanpura in D♯

D♯ — kali do — is where the male range starts to gleam. Qawwals and bhajan singers who ride over a full hall pitch here for the extra cut; it is also the shaded, velvet end of some female voices. A key with two doors, in other words.

Sangat holds the drone either way: real tanpura plucks at D♯, a deeper or brighter voice, and 18 tunings, each annotated with where it is used.

Nothing to install and nothing to sign up for: the tanpura, whole, is free. Open the app and it is already humming in your key.
