Eine kleine Nachtmusik
Serenade in G major · K. 525
Context
History of the work
Mozart entered the Serenade in G major in his thematic catalog on 10 August 1787, while he was working in Vienna. The surviving work has four movements. Mozart’s catalog describes five, so a minuet and trio is presumed lost.
The first movement is often used to introduce sonata form because its contrasts are unusually easy to hear. A bold unison statement opens the movement. A more graceful second theme arrives after a transition, and the development unsettles familiar material before the recapitulation restores the home key.
Inside the score
Music theory and form
A tonic fanfare
The opening outlines the G-major triad and answers it with quick repeated notes. Strong tonic and dominant gestures establish the key with theatrical certainty.
Balanced phrases
Short units answer one another with clear cadences. Mozart’s symmetry sounds effortless, but small extensions prevent the music from becoming mechanical.
Sonata-form drama
Exposition, development and recapitulation turn key relationships into a narrative of departure, instability and return.

Common questions
About Eine kleine Nachtmusik
What does Eine kleine Nachtmusik mean?
Literally, “a little night music.” Mozart’s catalog calls it a serenade, a flexible genre associated with evening entertainment.
Was a movement lost?
Mozart listed five movements, while four survive. Scholars therefore infer that a minuet and trio once stood between the opening Allegro and Romance.
