An Introduction to Jazz Book 1

I have just completed a new book called "An Introduction to Jazz Book 1." Just as the title says I created this book as a fun introduction to playing jazz for beginner/intermediate piano students. The first 3 songs are based on the 12 bar blues form which is the most standard form of music in jazz. The next 3 songs are based on classic jazz standards written by Duke Ellington. There is also a CD that goes with the book. The CD has 3 tracks for each song. One track is the full band including the piano. The next track is the full band without the piano and the 3rd track is solo piano.
I uploaded one of the songs on youtube and the sheet music of this song as well as the mp3 can be downloaded on my website.
