Musical leaf

The musical leaf is one of any leaves used to play music on. It goes by many names, including leaflute, leaf flute, leaf whistle, gum leaf, and leafophone.

In Cambodia, it is called a slek (Khmer: ស្លឹក) and is played by country people in Cambodia, made from the leaves of broad-leaf trees, including the sakrom and khnoung trees. It is also known as phlom slek, 'blow leaf.' To play a leaf, the musician curls the edge of a leaf into a semi-circle (along the leaf's long edge) and "places the arch between the lips", making sure that the leaf is touching both upper and lower lips. The leaf vibrates in contact with them as the player blows air across it. The player can control the pitch of the noise with their upper lip.
