Recorder for Absolute Beginners

This book is for kids or adults who are absolute beginners in music. I tried to write it as simply as possible. I use an "easy-to-play" visual aid so any beginner can play music quickly. No previous knowledge is necessary.
Every song has a large and simple 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 are 22 songs and 2 options to help children begin to play right away.
PLAYING BY LETTER CIRCLE
PLAY WITH THE MUSICAL STAFF
The player can first follow the circles and then repeat with the classic note symbols and staff. The helpful letters are always above the notes.
There are 3 parts in this book. They are equal to 3 levels.
Level 1
Songs that are played in one octave. All songs here appear twice: once written with circles and the next time with classic music notes. This will help kids remember the staff notes.
Level 2
In this part, you will find one version with both circles and notes and a more advanced version of the song with notes and musical notation.
Level 3
Here, the first two songs are versions of the same melody (different combinations of notes) written with circles and notes. This is important so that the beginner can see how the same melody can be played in different keys.
