PRINCETON, N.J. — Glancing at the lineup for the Golandsky Institute's annual International Piano Festival here, one might initially assume that it's yet another laudable program to put young classical artists on a solid career path, starting on the right (or correct) foot. Why, then, is one of the festival's most important recitals by the well-into-middle-age pianist Ilya Itin?The Golandsky Institute actually has a much broader reach, to pianists young, old, professional and otherwise, to acquire a piano technique with minimum danger of injury and to play without pain, no doubt the indirect legacy of pianists such as Gary Graffman and Leon Fleischer who, at the height of their considerable careers, lost the use of their right hands. Itin, who placed well in the prestigious Leeds Competition and has a good career in Europe and the Far East, is apparently the institute's poster person. The idea is the physical freedom that allows pianists to be all that they can be. Music education veterans say that many such institutes exist with similar missions.
