Eine kleine Nachtmusik

Eine kleine Nachtmusik is the name given to the Serenade No. 13 for strings in G major, K 525 by Wolfgang Amadeus Mozart. It is one of his most popular pieces and the opening tune is heard in many places, e.g. on mobile phones.It was composed in 1787 and is a serenade for strings.

The title Eine kleine Nachtmusik means literally: "A little Night Music". "Nachtmusik" was a title which was often given to serenades in the 18th century. A serenade in the 18th century was a lighthearted piece of music, often played during feasts. This serenade is written for two violins, viola, and cello and possibly a double bass as well. It is either performed as a string quartet (just four players) or by a small group of instruments, in which case at least one double bass is normally added.

 The structure of the music 

There are four movements:

 I. Allegro (fast)
 II. Romanze: Andante
 III. Menuetto
 IV. Rondo: Allegro

The first movement has this famous opening tune:

The first theme

The movement is in sonata form. A short while after the famous opening theme comes a second theme which is more graceful and in D major, the dominant key of G major. The first part (exposition) closes in D major and is repeated. The next part (development section) begins on D major and goes to other keys before the music returns to G major for the last part (recapitulation).

The second movement is a "Romanza".  It is marked "Andante" ("at a walking pace").  It is gentler and slower than the first movement.  Three tunes are heard during the movement, which has an ABACA structure.

The third movement is a minuet and trio (ABA) in G major.

The fourth and last movement is in sonata rondo form. This finale returns with the liveliness of the first movement.
