I'm a teen violist getting ready for college and
I was wondering what was a good...
An unaccompanied work
One movement from standard sonata
One movement from Bartok, Walton, or Hindemith
concertos or a virtuoso movement from standard
Are you looking for audition pieces?
I think that questions regarding college auditioning reportoire should be directed to the dean(s) of music at the college or university that you are interested. Not all schools have a dean of music but there is always someone heads the music dept.
