Some "popular" genre musicians have had significant classical training, such as Billy Joel, Elton John, the Van Halen brothers, Randy Rhoads and Ritchie Blackmore. Moreover, formal training is not unique to the classical genre. Many rock and pop musicians have completed degrees in commercial music programs such as those offered by the Berklee College of Music and many jazz musicians have completed degrees in music from universities with jazz programs, such as the Manhattan School of Music and McGill University.
