You recognize the intro to Billy Joel's Piano Man, but what does he play behind his vocals?
Your ears perk up when you hear Elton John play the opening GMaj7 chord that signals Bennie And The Jets, but do you keep listening to the piano once he starts singing?
You love the gentle piano accompaniment that begins Adele's Someone Like You, but do you keep focused on it throughout the whole recording.
Give it a try. Tune out the vocal sometimes and focus on the background piano part. It's a whole universe of piano music, just waiting for you to discover it!
