Serenade for Strings in G Major KV 525 is much better known to the world as Eine Kleine Nachtmusik, composed by Wolfgang Amadeus Mozart in 1787.
The title translates as "A Little Serenade." These four movements for string orchestra are probably Mozart's best-known piece. It is not known whether the composition was written for a particular evening party, of whether it is a kind of idealization of the form. Essentially, this work is to the symphony as a sonatina is to a sonata: A dancing first movement with two contrasting themes but only a small symphonic development, a lovely song in rather fast a tempo for the second movement, a sweet minuet, and a frisky conclusion.
