Tanpura Drone C# : Sa-Pa|| तानपुरा : पहला काला, सा-प || Meditation & Practice

The tanpura (तानपूरा; or tambura, tanpuri) is a long-necked plucked string instrument, originating from India, found in various forms in Indian music. It does not play melody but rather supports and sustains the melody of another instrument or singer by providing a continuous harmonic bourdon or drone. A tanpura is not played in rhythm with the soloist or percussionist: as the precise timing of plucking a cycle of four strings in a continuous loop is a determinant factor in the resultant sound, it is played unchangingly during the complete performance. The repeated cycle of plucking all strings creates the sonic canvas on which the melody of the raga is drawn. The combined sound of all strings, each string a fundamental tone with its own spectrum of overtones, supports and blend with the external tones sung or played by the soloist.
The name of the instrument derives from Persian تنبور (pr. tanbūr) where it designates a group of long necked lutes (see tanbur). Hindustani musicians favour the term 'tanpura' whereas Carnatic musicians say 'tambura'; 'tanpuri' is a smaller variant sometimes used for accompanying instrumental soloists.
