Bansuri Bamboo Flute Making and Tuning

बाँसुरी (Bansuri)

The bansuri (बाँसुरी) is Nepal and India's primary classical bamboo flute — a side-blown transverse flute made from a single bamboo culm with 6 or 7 finger holes. Nepal's bansuri-making tradition is concentrated in Kathmandu Valley and the Terai, where specific bamboo species (Bambusa tulda — wanjee in Nepali) provide the naturally hollow, consistent-diameter culms required. The defining technical knowledge is the hole position calculation and drilling: the 6-7 finger holes are positioned using a system derived from the length of the flute player's fingers — each hole is spaced based on the flute maker's own hand measurement (finger-length from blow hole to first tone hole, and proportional spacing between subsequent holes). This body-proportion system produces a flute tuned to that maker's hand — which is why a bansuri player often prefers flutes made by a single maker.
