The are in the book songs without text. Check out samples from books: http: //osos.sweb.cz/Preview-Anglo-concertina.pdf Youtube demonstrations: https: //www.youtube.com/playlist?list=PLDcJRi8rTK0ECjmXDtrzm0RvJYvN_rvql Usual kalimba which you can buy is tuned a4 c5 c4 a4 a3 f4 e4 e5 b4. You can not play so much songs on it. But you can retune it on tone g4 and you will receive more possibilities. I tried to gather and composed songs in this book. How to tune the lamella? Good tipes are on the internet (YouTube). Have a nice moments with kalimba.
