The Keyboard Play-Along Series helps players learn to play their favorite songs quickly and easily. They can follow the music, listen to the CD to hear how the keyboard should sound, and then play along using the separate backing tracks. The melody and lyrics are also included in the book for singing, or simply as help to follow along. The audio CD is playable on any CD player. For PC and Mac users, the CD is enhanced so you can adjust the recording to any tempo without changing pitch!
