Pune flautist Sameer Inamdar's innovative musical instrument called the Sameer Flute has been featured in the Limca Book of Records. Inamdar calls the flute, born out of five years of research, "a symbiosis between music and science". Not only is it thrice the length and almost twice the diameter of a normal flute but also has 10 notches cut into it as compared to the traditional six. "We can increase the range of the flute or the octave rating on this," he says, adding, "A normal flute will not allow a flautist to change the pitch from low to high and vice versa very quickly without a very noticeable heaviness to it. My flute allows a user to do that instantly." An understanding the physics of the flute was done with the help of scientist Uday Ghatge of Brain Chambers Research Institute of Kolhapur. The instrument is based on the Helmholtz Resonance Principle, which also enables upto three times more amplification of sound along with deep resonance. A student of the Dhrupad Gharana, Inamdar says the flute allows a user to understand the depth of Dhrupad music. "A normal flute will allow for a 2.75 octave range. This one goes close to four octaves," he says. The citation received from the Limca Book of Records committee states, "Sameer D Inamdar's creation, Sameer flute covers 3.66 octave. The flute is unique in the make which provides it the necessary quality to cover an extended range of octaves". Sameer has added a small chamber, Tumba, below the flute to achieve this feat. A normal flute covers three octave. Sameer Flute helps a flautist to avoid carrying different flutes for a recital.
