An online tanpura in D

D — safed do — is C♯ with the lights turned up: still male territory, but brighter, more forward. Bhajan singers reach for it, younger voices often start here before gravity has its say, and it suits repertoire that wants lift rather than gravitas.

In Sangat, a tanpura in D is real string plucks at the key. Three plucking styles set how the strings roll; a fine tune in cents settles the last few hair-widths when you are matching an old harmonium that has drifted.

Eighteen tunings cover everything from a Kharaj Sa two octaves of calm below, up to a high Ma for ragas that lean on it. All of it is free, with no account — the browser tab is the whole setup.
