MyKey is the Singer's Friend! Whether you're going out to a piano bar, enjoying karaoke or preparing for an audition, MyKey allows you to track song title and composer, your personal best key and starting note, type (ballad/uptempo/B'way/standard/patter), whether you have the sheet music, where you keep it, and even the date and location of your last performance or audition using the song. Demo version (like some accompanists) functions only in limited keys; register to magically expand its musical acumen to all 13 keys and starting notes.
