I've been thinking about a movie which I saw as a kid in 80-90xx. Here are some scenes which I remember:
A boy has uncontrolled telekinetic abilities and he is on the run from people (officials) who want to investigate it.
His friend who plays a musical instrument (violin or smth else) helps him to train his abilities. Puts a glass/bottle/plate on a table and tells him to move it without dropping.
In the end government officials ask him to handle a special bomb filled with liquid very high explosive material. The bomb was stuck on a ramp of some building. The boy successfully prevents explosive liquid from spilling out of the bomb and moves it with his powers to the ground.
In the last scene the boy helps to his musician friend to get a soloist party with an orchestra after demonstrating to a theater director his powers.
Appreciate to find out what was the movie title.
