Kalimbas are plucking instruments which you simply play with your thumbs. Therefore they are also called thumb pianos.
The “Mbira” or “Sansa” which are the African instruments for what we now know as a Kalimba, originated from a simple halved calabash, a turtle shell or half a coconut as a resonance body.
Spring is a transition as we come from the cold winter towards the warm summer.
Therefore the Zaphir chime which represents Spring - the Crystalide - is a combination of summer and winter.
You will find a mix of tunes from the Blue Moon (Winter) and the Sunray (Summer) here.
