The Tic Code (1997)

From NetFlix: Miles (Christopher George Marquette), a 12-year-old boy living with his mother in New York City, is inspired by the jazz scene and already displays a remarkable gift as a pianist. But he also suffers from a mild case Tourette's Syndrome, which alienates him at school. When Miles meets saxophonist Tyrone Pike (Gregory Hines), one of his idols, the two become friends and teach each other how to deal with their condition and life by playing music. 1997 90 minutes.

A fine film. Gregory Hines was great. Good stuff about Tourette's
