While the Thomas Bothe "2B" kalimbas are charming and delightful, they have one major drawback - there is a dearth of instructional materials for them. This is mainly because each kalimba Thomas makes is an individual, tuned to its own unique tuning, and so it's not really possible to write a book for each one.
I had a great idea about making it possible for people to be taught how to play 2/B kalimbas. The idea came about this way: Over the last 10 years I produced several instructional books/downloads for four different Hokema sansula tunings (a sansula is a special kind of kalimba). While pondering how to make 2/B's teachable, it hit me: why not offer the 2B/9 kalimbas tuned to these four sansula tunings so people could use the sansula books to learn their 2B instruments? So that is what we have done, and below I describe each of the books which can be used with our new "alt" 2B kalimbas.
