valiha

Aside from recreational music, the valiha is also used for ritual music to summon spirits. It is commonly thought in Madagascar that the valiha is "inherited from King David", as part of a larger origin narrative of Jewish provenance of Malagasy people.

Historically the instrument was made of the bamboo Valiha diffusa, but in the modern day "bamboo species with longer internodes" are used. The bamboo poles used for building the valiha are chosen between diameters of 5 to 10 cm and preferably cut within a length of 35 to 180 cm. The valiha generally has 21-24 strings. Historically these were formed of strips of the bamboo body, prised up and raised by small calabash or wooden bridges that also act as movable tuners, but in the modern day the strings are often made of unwound bicycle brake cable tied through nails, though serious players may use standard guitar or piano strings used for churches and folk bands. A variant instrument, the marovany, is similar in concept but boxlike rather than tubular, and made of wood or sheet metal.

One of the most celebrated valiha players of the twentieth century is Rakotozafy (born 1938). The majority of Rakotozafy's few recorded performances were made live at the central studio of Malagasy Radio. Sylvestre Randafison is another celebrated valiha artist considered a cultural icon in Madagascar.
