My gift to the kalimba world is kalimba tablature. It is expressive and elegant. It can display any sort of music, and it reflects my internal conceptualization of the kalimba and its music.
However, not everyone likes my vertical tablature.
If the tablature is too much for you, you might want to try the Numbers-based approach.
Soon, I am going to have a full length Numbers-based book available for sale. Until then, I offer you this short "demo version" of the book for free.
