|Pungi or Bin is the snake charmer's instrument.
The word "Bin" has always been somewhat problematic. The term "bin" is a very common corruption of the Sanskrit word "Vina". However the term bin/ vina implies a stringed instrument. It is more likely that the term "Bin" is a corruption of the Sanskrit "Venu" (i.e., bamboo) which would clearly place this instrument in the class shared by flutes.
