Ocisanji of Vachokue At Cangamba the Vachokue have an instrument consisting of eight slats of wood which vary in length and thickness. These sounding boards are attached to two parallel cords which are kept tight by two assistants. The performer taps the wooden slats with two sticks terminating in balls of wax. This is the well-known marimba, but the gourds which are usually fastened under the slats of wood were absent in this instance. The instrument ocisanji is played well by only a few men. It consists of a wooden board, often well carved, on which there are from eight to nineteen thin keys of metal. These can be pushed backward and forward in their bridge so as to alter the vibrating length and pitch of the note. The pitch may also be varied by placing small balls of wax on the under side of the keys. When the instrument is held between the palms the player's thumbs are in position for stroking the keys. Sometimes ocisanji is played inside a wide gourd (Plate XXII, Fig. 5).
