The Mbira (Thumb Piano)

 

 

A Brief History

The mbira has been has been part of the sub-Saharan African culture for 800 years. Sometimes played as a solo instrument, it is more often used to accompany other musicians, singers and dancers. The African mbira can very widely in style and name as each tribe will create a distinctive version using locally available materials. The smallest is a 6-note instrument made by the Kalahari Bushmen while the most sophisticated 33-note version is found in Zimbabwe. The name mbira is used in Zimbabwe and is known throughout much of Africa, but other names are used like kalimba in Kenya, ikembe in Rhuanda, and the name likembe in the Congo, are few other less common names are sanza, sansa, marimba, marimbula. In Europe and the western world the instrument is known more by the generic names of finger harp, gourd piano, and thumb piano. The thumb piano name was most likely derived because the instrument is played by plucking the tines or tongues with one’s thumbs to sound individual notes. Hugh Tracey, an Englisman, became fascinated with African music during his travels to Rhodesia (now Zimbabwe) in the 1920s. In the early 1960’s he received a registered trade mark for a version of the mbira call the Kalimba, which translates to little music. The diatonic instrument soon became popular around the world. The mbira is well suited for playing harmonies in western music but it’s wide acceptance may be due to the simple design and relative ease by one can learn to play the instrument.

Description

The mbira is a simple instrument, normally having a wooden sound box and soundboard. Six to thirty-three keys, tongues, or tines are mounted across two metal or wooden bars on top of the soundboard. Typically one bar holds the keys in place and permits them to be tuned to the proper notes while the bar closest to the sound hole serves as a bridge which transfers vibrations of the keys to the soundboard and sound box. The keys are plucked with the thumbs and the various lengths of the keys produce different notes. Some versions have extra sound holes on the sides or the back of the instrument which can be covered with the fingers as a way to change the resonance of the instrument and provide a tremolo affect.

Thumb Pianos Handcrafted by Steven Stapleton can be made of a variety of solid woods including cherry, curly maple, walnut, mahogany and various exotic woods such as bloodwood, purpleheart and sassafras. The soundboard is made of spruce, western red cedar or redwood and metal bars and tines are used. The instrument is sanded to 7000 grit inside and out. Two coats of lemon oil are applied to the inside and twelve coats of tung oil are applied to the outside, with a light sanding between coats, for a smooth finish that allows the instrument to vibrate better, providing a fuller and richer sound. A tuning chart and sample song are provided with each instrument.
