Borassus flabellifer
The main part of the "sasando" is a bamboo tube that serves as the frame of the instrument. Surrounding the tube are several wooden pieces serving as wedges where the strings are stretched from the top to the bottom. The function of the wedges is to hold the strings higher than the tube surface as well as to produce various length of strings to create different musical notations. The stringed bamboo tube is surrounded by a bag-like fan of dried "lontar" or palmyra leaves ("Borassus flabellifer"), which functions as the resonator of the instrument. The "sasando" is played with both hands reaching into the stings of the bamboo tube through opening on the front. The player's fingers then pluck the strings in a fashion similar to playing a harp or kacapi.
