Explanation:

A run - on sentence combines two or more independent clauses without proper punctuation or conjunction. In "Many people play a musical instrument music can be soothing", there are two independent clauses ("Many people play a musical instrument" and "music can be soothing") joined without proper separation. Adding a semicolon after "instrument" properly separates the two independent clauses.

Answer:

Adding a semicolon after instrument
