Mbira musical instrument - Kalimba - African craft
Mbira are a family of musical instruments, traditional to the Shona people of Zimbabwe. They consist of a wooden board with attached staggered metal tines, played by holding the instrument in the hands and plucking the tines with the thumbs, the right forefinger, and sometimes the left forefinger.
Various kinds of plucked idiophones and lamellaphones have existed in Africa for thousands of years. The tines were originally made of bamboo but over the years metal keys have been developed. These types of instrument appear to have been invented twice in Africa: a wood or bamboo-tined instrument appeared on the west coast of Africa about 3,000 years ago, and metal-tined lamellophones appeared in the Zambezi River valley around 1,300 years ago. Metal-tined instruments traveled all across the continent, becoming popular among the Shona of Zimbabwe (from which the word mbira comes) and other indigenous groups in Zimbabwe and Mozambique. The mbira was differentiated in its physical form and social uses as it spread. Kalimba-like instruments came to exist from the northern reaches of North Africa to the southern extent of the Kalahari Desert, and from the east coast to the west coast, though many or most groups of people in Africa did not possess mbiras. There were thousands of different tunings, different note layouts, and different instrument designs, but there is a hypothetical tuning and note layout of the original metal-tined instrument from 1,300 years ago, referred to as the 'kalimba core'. In the mid 1950s mbira instruments were the basis for the development of the kalimba, a westernized version designed and marketed by the ethnomusicologist Hugh Tracey, leading to a great expansion of its distribution outside Africa.
