The Mandolin Play-Along Series will help you play your favorite songs quickly and easily. Just follow the written music, listen to the online audio to hear how the mandolin should sound, and then play along using the separate backing tracks. Standard notation and tablature are both included in the book. The audio is accessed online using the unique code inside each book and can be streamed or downloaded. The audio files include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right.
