In 2015, the Musicfest added a formal educational component to its offerings: the Buzzards Bay Musicfest International Performance Institute. The Institute is an intensive (by audition) seminar designed to foster the musical development of young instrumentalists, allowing them an unparalleled opportunity to train with world-renowned musicians and expert instructors.

This year’s violin seminar will include daily technique classes taught by Charles Stegeman, as well as master classes featuring internationally-renowned master clinicians Ole Böhn, Edith Markman and Eric Tanner.

Master classes for pianists will be taught by David Allen Wehr, an international soloist and collaborative pianist in residence at the Musicfest.

The 2016 Institute will take place from July 11 to 17, and students ages 14 and up are encouraged to apply. Scholarships are available. For more information, visit www.buzzardsbaymusicfest.com/international-performance-institute or email performanceinstitute@buzzardsbaymusicfest.com.
