If you would like to play 'Replay' by IYAZ and Sean Kingston on the piano you first start with playing a C and G chord on the left hand. On the right hand you will play the four notes to the first part of the song. The left hand will move down and play an A minor chord that is an A and E. Your right hand will then finish off that phrase. Now your left hand with play and F major chord that consists of an A and a C. While this happens your right hand will be finishing the music phrase. Now your left hand will play G and D which is a chord. With this your right hand will play E. Now, you should put all of these phrases together to create the song. If you want this to sound different replace the G chord there with a G sharp chord. Now, you will play an A minor chord and your right should finish the phrase. Now play an F major chord. Now move up to a c major chord on your left hand. Now, once you get the hand of it you can improv on it and have fun with it.
