Bansuri - Bansuri Flute - Bansuri instrument - Indian Bansuri flute

The Bansuri flute is one of the three original forms of rendering Indian Classical music according to ancient scriptures - Vaani (Vocal), Veena (String) and Venu (Flute). According to Hindu mythology, it is the instrument of Lord Krishna and is thus very popular for playing folk music. The word bansuri originates in the Sanskrit bans (bamboo) + swar (musical note)

The Hindustani bansuri flute usually consists of a blowing hole, six fingering holes and one tuning hole (though in some cases, flutes do not have tuning hole). The pitch of the bansuri varies depending on the length and diameter of the bore. The longer the flute, the deeper its pitch. However, longer flutes are also difficult to blow and finger. To balance this tradeoff, most Hindustani bansuri players tend to choose bansuri with pitch E (safed teen) and this flute is approximately 30" long.

Naturally, the bamboo suitable to make bansuri is not available freely. In its entire length, the flute bamboo should not have a node. If you think about it, it is not common to find a bamboo that is thin, straight and yet does not have a node for 30". Such bamboo species are only found in the jungles of Indian states of Assam and Kerala. Before making the flute, the bamboo is seasoned so that the natural resins strengthen it. It is then blocked with a piece of cork or rubber stopper from one end. musicalinstruments-list.blogspot.com Holes are then burned into it as drilling holes often breaks the bamboo. The proportions between bamboo length, bore, diameter of each hole and the location of stopper cork are extremely critical for getting the tuning of the bansuri right. Strings are then tied around the bamboo for both decoration and protection.

The Bansuri is a versatile instrument. It can easily produce all basic elements of Hindustani music variation such as meend (glide), gamak, kan. Versatile bansuri players also produce emotions in their music through variations in blowing style.
The Bansuri is a very simple instrument. Unlike string instruments, it does not need tuning once it is tuned by the flute maker. However, as Hariji puts it, it is Krishna's instrument and the Lord has made it deceptively simple. To become adept in the bansuri, one needs many months of practice.

Famous masters of the bansuri include Pt. Pannalal Ghosh, Pt. Hariprasad Chaurasia, Vijay Raghav Rao, G. S. Sachdev, Pt. Devendra Murdeshwar, Pt. Raghunath Seth, Ronu Majumdar and Nityanand Haldipur.
