The kayamba is a flat musical instrument, a shaken idiophone, used in the Mascarene Islands to play sega and maloya music. It is called maravanne in Mauritius, or caïamb or kayanm in Reunion.
Kayambas are made of reed (or sugar cane flower stems) and its tubes filled with jequirity or canna seeds.
They are also played in some East African countries like Kenya.
