Your digital headquarters for Staunton, VA's Heifetz International Music Institute. Purchase concert tickets, view archival performance videos, and catch up on all the latest offerings from the Institute's exceptional students, alumni, and faculty. The Heifetz International Music Institute is a non-profit organization dedicated to the artistic growth and career development of the most talented and promising young musicians in the world. We believe there are specific factors that distinguish a good performance from a great one, an emerging musician struggling to form their artistic identity from a complete performer who will establish a notable career. We seek to know, and to teach, what those factors are and how to achieve them. Through the innovative Performance & Communication Training method, the Institute leads musicians to convey the emotion of the music they’re performing, explore their full creative potential, express their individuality, and redefine the concert experience. http://www.publicmediaapps.com https://heifetzinstitute.org
