'spielen' and 'interpretieren' can both be used with music, theater, or other artistic works. 'spielen' first describes the action: someone plays an instrument or a role. 'interpretieren' goes one step further and means that someone presents a work in their own way, with personal expression and understanding. The words can be confused because a person who is interpreting something often also plays or performs it. 'spielen' is more neutral and simpler in everyday language. 'interpretieren' fits especially when the focus is on style, feeling, and artistic presentation.
