(Piano Play-Along). Your favorite sheet music will come to life with the innovative Piano Play-Along series! With these collections featuring online audio, piano and keyboard players will be able to practice and perform with professional-sounding accompaniments. Containing eight cream-of-the-crop songs each, the books feature new engravings, with a separate vocal staff, plus guitar frames, so players and their friends can sing or strum along. The audio features two tracks for each tune: a full performance for listening, and a separate backing track that lets players take the lead on keyboard. The high-quality, sound-alike accompaniments exactly match the printed music. This volume includes eight of Bruno Mars' best, including: Count on Me * Grenade * It Will Rain * Just the Way You Are * Locked Out of Heaven * Marry You * Treasure * When I Was Your Man. 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.
