Assume the "B Flat Hand Position" on the piano with your right hand by placing your pointer finger on Middle C, your thumb on B Flat, your middle finger on D and your ring finger on E Flat.
Say "In-di-an-a" out loud four times to get a feel for the rhythm of the ostinato pattern. The pattern consists of 16th notes in a 4/4 meter. Saying "Indiana" or "Pennsylvania" helps keeps the rhythm steady.
Play the 16th notes in this order :
Eb Bb Eb Bb D Bb D Bb C Bb C Bb D Bb D Bb
Repeat the ostinato pattern throughout the song. The ostinato stops just before each chorus during the lyrics, "Slow down," and resumes during the verses. It also stops during the bridge and resumes during the song's tag.
Play two more measures of the ostinato to end the song, slowing down during the last measure. Finish by playing one last Eb and hold.
