MBIRA ; is a simple soundboard or soundbox with wooden (typically cane) or metal keys or tongues (called lamellas) attached on the top. The soundbox is typically made from a calabash (gourd) or wood, and often the metal keys (tongues) were made from old spoon handles, bicycle spokes or spring wire that were cut and hammered to the desired shape. The keys (tongues) are plucked with the thumbs, or with combinations of thumbs and fingers. The keys usually consist of 6 to 33 metal keys (tongues) mounted across two bars (or wooden dowels) at one end attached to the soundbox with another wooden dowel holding them in place
HISTORY: The mbira has been an important instrument in sub-Saharan Africa and has played a part in African culture for 800 years. Although it can be a solo instrument, it is more commonly used as an accompaniment to singers, musicians and dancers. It is not uncommon for the native African instruments to allow solo harmonization, but typically, harmony in African music serves as a variation to the theme being performed.
Many versions of the mbira exist with tribes creating distinctive performance styles and names for the instrument. They vary widely in appearance, size, materials, and tuning from the smallest 6-note models of the Kalahari Bushmen, to the sophisticated 33-note instrument found in Zimbabwe. The name mbira is know throughout much of Africa, but regionally, the name mbira is more commonly used in Zimbabwe, while the name Kalimba is used in Kenya, the name ikembe is used in Rhuanda, and the name likembe is used in the Congo, while other names are bit less common such as sanza, sansa, marimba, marimbula, there are more generic names of finger harp, gourd piano, and thumb piano that are often used in the west.
The mbira is also known as the thumb piano, because one's thumbs are used to pluck (or more accurately depress and release) the metal strips (tongues or lamellas) that sound particular notes. It is common for two mbiras to play together where one covers the melodic accompaniment of the singer while the other plays the bass line (or bourdon). Some mbiras have few tongues and others have many. Some of the more sophisticated instruments have two sets of tongues for one performer to play melody and harmony, or melody and bass line on the same instrument.
In the 1920's, Hugh Tracey came from England to Rhodesia (now Zimbabwe) to help his older brother run a tobacco farm. He became fascinated by the local music culture and created the Kalimba, a version of the mbira. Introduced by Tracy in the early 1960's, Kalimba was the registered trademark for his diatonic instrument that soon became popular around the world. The word kalimba literally means little music. It was well suited for Western music and made it easy for the performer to play harmony using both thumbs.
