Pandit Raghunath Seth made many breakthroughs in the technique of flute making and playing. He is well known for adding a bamboo key to his bansuri that makes previously impossible phrases, such as the meend (Glissando) between Ma and Pa, easily playable. He also added an 8th hole which allows the player to extend the range of Indian bamboo flute, further into the lower octave.
