The musical bow is a simple string musical instrument part of a number of South African cultures, also found in other places in the world through the result of slave trade. It consists of a flexible, usually wooden, stick 1.5 to 10 feet (0.5 to 3 m) long, and strung end to end with a taut cord, usually metal. It can be played with the hands or a wooden stick or branch. Often, it is a normal archery bow used for music.

History

Although the bow is now thought of as a weapon, it is not clear whether it was used in this way originally. A cave painting in the Trois Frères cave of southern France, dated to around 13,000 BCE, displays a bow being used as a musical instrument, so this use certainly has a long history.[1] Musical bows are still used in a number of cultures today. It can be found as far south as Swaziland, and as far east as eastern Africa, Madagascar, and Réunion. and also outside of Africa, as in the case of berimbau, malunga (derivations of the African musical bow) or the Appalachian mouth-bow.

Playing method

The usual way to make the bow sound is to pluck the string, although sometimes a subsidiary bow is used to scrape the string, much as on a violin. The Onavillu of Kerala sounds when struck with a thin stick. Unlike string instruments used in classical music, however, they do not have a built-in resonator, although resonators may be made to work with the bow in a number of ways.

The most usual type of resonator consists of a gourd attached to the back of the string bearer. The bow may also be stood in a pit or gourd on the ground, or one end of it may be partially placed in the mouth. This last method allows the size of the resonator to be varied as the instrument is played, thus allowing a melody to be heard consisting of the notes resonating in the player's mouth. As well as these various forms of resonators, the bow is frequently played without a resonator at all.

In Africa the musical bow is played usually by a solo performer. In Capoeira, the berimbau is played as part of the roda, a musical group standing in a circle, in the centre of which the Capoeiristas perform or play. The Appalachian mouth-bow can be played amplified in old-time music jams.

In Africa

Due to the nature of their construction and playing, musical bows are quiet instruments, therefore needing a resonator to resound. The resonator can either be a gourd (as in uhadi, umakhweyana, segankure, xitende, berimbau, etc.) or the player's mouth (as in umrhubhe, umqangala, tshihwana, xizambi, etc.)

Musical bows are the main instruments of the Nguni and Sotho people, the predominant peoples of South Africa. Historians believe that many of the musical bows came from Khoisan peoples. Although there are many differences between musical bows, all of them share two things: a resonator, and at least two fundamental notes.

The strongest notes are the fundamentals, the deepest notes produced by the string, whereas the higher notes (the harmonic partials) are produced by the resonator.

There are at least two fundamentals notes produced by all musical bows, an open (when the player does not shorten it or touch it) and a closed (where the string is shortened or stopped by the player's hand). In Xhosa they are called vu (from the word Vuliwe, 'open') and ba (from Banjiwe, 'held') respectively. These two notes can already be on the string, if it is divided or stopped by a string attached to the gourd, as in the case of umakhweyana, xitende, berimbau, hungu, etc. The pitch difference between a vu and a ba is usually about a whole tone. In certain places in can be closer to a semitone (e.g. Zulu) or closer to a minor third (Tsonga).

Some of those instruments have more than two notes, for example the Zulu umakhweyana and the Tsonga xitende have three, whereas the Venda tshihwana has four.[2]

Other names

Musical bows are known by various names in the different languages of South Africa - some refer only to musical bows using gourds as resonators, others using the mouth:[2][3]
