The bansuri is a North Indian transverse flute made from a single piece of bamboo. It is also known as the venu, and is an essential part of Hindustani classical music. The bansuri has a very distinctive, mellow sound, and is often used as a solo instrument or in accompaniment to other instruments. The bansuri is traditionally used in two main playing styles: the khayal and the thumri. In the khayal style, the bansuri is used to play melodic phrases which are often improvised. In the thumri style, the bansuri is used to provide a rhythmic accompaniment to the vocalist or other instruments. The bansuri is a very versatile instrument, and can be used to play a wide range of music, from classical to popular. It is also a popular choice for film and television soundtracks.
