At New York City Ballet, **Works inspired by the compositions of Johann Sebastian Bach** brings ballet into close contact with Bach’s musical architecture, using phrasing, counterpoint, and structure as the choreographic engine. Performed live by the company, the program treats the score less as accompaniment than as a set of rules the dancers test and translate in real time. Bach’s music has long been part of New York’s concert life, and NYCB’s continued return to it reflects a local tradition of measuring dance against rigorous classical form. One clear effect is that the dancing is asked to sound, not just look, precise.
