Eine kleine Nachtmusik (Serenade No. 13 for strings in major), K. 525, is a [bad word] for a chamber ensemble by Wolfgang Amadeus Mozart. The German title means "a little serenade," though it is often rendered more literally but less accurately as "a little night music."[1] The work is written for an ensemble of two violins, viola, and cello with optional double bass, but is often performed by string orchestras.[2]
