The tambin (also sereendu, fulannu or Fula flute) is a diagonal diatonic flute without a bell, made from a conical vine, with three finger-holes and a rectangular embouchure with two wings on either side. It is considered the national instrument of the West African Fula. The flute was used in the 2018 Marvel movie Black Panther.
