This is my 1st CD for backing tracks for playing your American Indian Flute with. There are 11 tracks taken from the Winning Pnaci CD at the Indie Channel Music Awards 2013. You can use any Key flute with 9 out of the 11 songs. Two of the songs you will need to use a E flute because you will be playing with songs that have a E flute in them also. "Got Flute" and "Happy Fluting"
