The standard tuning for 4-stringed tanpuras consists of fifth, octave and tonic. Ragas without any fifth require different tuning - some traditional options for that purpose are given below. 5-stringed or 6-stringed tanpuras offer further variations. As an alternative to the traditional solutions many creative musicians make up their own tunings.
