TanpuraSa at Csafed ek

An online tanpura in C

C is the first white key — safed ek on a harmonium — and the Sa of singers who want weight under the voice. Dhrupad singers live here and lower; khyal baritones settle into C when C♯ feels a shade tight. If your voice fills a room from the bottom, this may already be your key.

Frequencies assume A = 440 Hz. Sangat has a fine tune in cents for an instrument that sits a little sharp or flat.

Tuning the first string

A tanpura's first string sets its colour; the other three hold Sa. With Sa at C:

  • Pa (G) — the default, right for most ragas.
  • Ma (F) — for ragas without Pa, such as Malkauns and Chandrakauns.
  • Ni (B) — for ragas where Ni is prominent, such as Bihag and Kalyan; komal Ni (A♯) for Kafi, Bhairavi and Jaunpuri.
  • Kharaj Sa — a deep drone an octave down, favoured in dhrupad.

Sangat has all eighteen tunings, each labelled with where it is used. Which tanpura tuning for which raga lists them all.

Is C your Sa?
