Sansula is modern development of the African kalimba (likembe, mbira). The "thumb piano" is mounted on a hide which lends the sound additional volume and resonance. Tipping the instrument on a flat surface achieves a wah-wah effect. If you mount a strap to put sansula on your belly, it can be modulated like berimbau using your belly (see demo video). Smart positioning of the keys let you play sansula with just one hand if you want.
