This book is a great help as I learn how to play the kantele I built from a Musicmakers kit. It assumes that the reader has no knowledge of how to read music or how to play the kantele. Lessons are divided into short exercises for familiarizing the student with both music notation, etc. and actual play.
There are plenty of "hands on" exercises to reinforce the lessons. The book comes bundled with short videos to help the student along, as well. The writing is clear and well edited. The explanation is adapted to the most basic concepts but not oversimplified. I am greatly looking forward to the time when I can start playing actual songs! (Lyrics are included, too.) But that will be a while.
