"Eine kleine Nachtmusik" is a piece by Mozart. It's usually translated with "A small serenade". I'm not sure whether the literal or the loose translation would be more fitting. Maybe it shouldn't be translated at all since this is the title of piece of music. Anyone care to help me out?

maybe a note saying that its a title from a song would be good? i am german but didnt know that this is a song from mozart :P
