Listen to Billy Joel on iHeartRadio

Billy Joel is helping aspiring keyboardists learn their craft. 

The rocker has given Stony Brook University a new piano.  But not just any piano.  The Bosendorfer Imperial Grand Piano is known as the "Rolls-Royce" of pianos, and is worth $250,000. 

It includes nine additional keys, which gives musicians and composers an additional octave to work with. 

The Bosendorfer is the second piano Joel has donated to the school.  A few years ago Billy contributed a Baldwin Grand Piano to Stony Brook's music department.
