It comes from Africa. It has a wooden sound-box with mother-of-pearl inlays.
It is played by plucking the steel tongues with the thumbs. A vibrato effect can be produced by covering or uncovering with the fingers the holes on the top.
Kalimbas can be tuned at will to produce different types of scales.
This is done by loosening or tightening the screws that hold down the tongues, which can in turn be pushed back and forwards on the bronze bridge.
They come with 20 notes tuned in diatonic, pentatonic or chromatic scales, the order of which is alternated from left to right.
Its original name is Mbira while in Europe is known as thumb piano.
This is a very practical instrument for music teachers, music therapists, or professional musicians, since it can be played by two instrumentalists at the same time.
Both Kalimbas belong to a same sound box but each one can be tuned to a different scale, for example, one can be tuned to a pentatonic scale while the other is tuned to a diatonic scale. In the lower part we can find two vibrato holes that can create distortion.
Each Kalimba is made of 10 tongues which can be tuned to the same or to a different tonic.
The tonic notes can be G or C.
Tuned to the key of C (10 tongues): C, D, E, F, G, A, B, C, D, E
Tuned to the key of G (10 tongues): G, A, B, C, D, E, F?, G, A, B
