KalaSudha online tanpura

KalaSudha Tanpura is a free tanpura drone that runs in the browser, made by KalaSudha Ltd, a social enterprise that runs concerts, recordings and an online academy for Indian classical music and dance. You choose your Sa by harmonium key or kattai number, fine-tune it in cents, set the first string to Pa, Ma, Ni or Sa, and play four, five or six strings in a lower or higher register. Further controls cover the fifth and sixth strings, the time between plucks, the jawari, a dry room or hall sound, and the volume of each string. It works in current Chrome, Safari, Edge and Firefox with no account needed.
