Watch Me Play! A Self-guided Music Course for Children

This book is for kids or adults who are absolute beginners in music. I tried to write it as simply as possible. That is why I use an "easy-to-play" visual aid so any beginner can play music quickly.
Neither kids nor their parents have to read sheet music or have a musical background. No previous knowledge is necessary. None at all.
Every song has a large and simple, color and letter-coded visual, along with traditional sheet music. The instruction is designed so that children begin with simple circles and gradually advance to reading notes using sheet music. I try to make this transition as easy as a game, where children advance to higher levels themselves.
There is a total of 22 songs and 3 options to help children to begin to play right away.
