Bansuri and venu are common Indian flutes. They are typically made of bamboo or reed. There are two main types; bansuri and venu. The bansuri is used in the North Indian system. It typically has six holes, however there has been a tendency in recent years to use seven holes for added flexibility and correctness of pitch in the higher registers. It was previously associated only with folk music, but today it is found in Hindustani classical, filmi, and numerous other genre. Venu is the south Indian flute and is used in the Carnatic system. It typically has eight holes. The venu is very popular in all south Indian styles.
