The bansuri is a transverse flute from India, the word bansuri originates in the Sanskrit with bans meaning bamboo, and sur meaning melody. It is one of the oldest musical instruments. All half notes, accidentals and microtones are produced by a unique fingering system. The finger holes have to be precisely covered either fully or half by the phalanxes of the fingers and not by the fingertips. This technique also simplifies the playing of longer bansuris. The standard quality of the Indian bansuris produce a quite beautiful sound, but their tuning is often not exactly to the western standard notes. It can happen that they sometimes sound slightly out of tune to the western ear.
