Exploring the Hokema B11 Kalimba
This 74 page book by Mark Holdaway, is full of instructional tips and tablature for 64 songs and exercises arranged just for the Hokema B11 Kalimba. The material starts out very easy, appropriate for a beginner, but progresses to provide challenges for better players - in other words, anyone can start on this book and there is room to grow!
I find the note layout for the B11 to be particularly nice and inspiring of really neat music.
Sound files for the songs can be downloaded for free.
