Whether you're a karaoke singer or preparing for an audition, the Pro Vocal series is for you. The book contains the lyrics, melody, and chord symbols for eight hit songs. The CD contains demos for listening and separate backing tracks so you can sing along. The CD is playable on any CD, but it is also enhanced so PC & Mac users can adjust the recording to any pitch without changing the tempo! Perfect for home rehearsal, parties, auditions, corporate events, and gigs without a backup band.
