Mozart: Serenade No.12 in C minor “Nachtmusik” K388 - wind dectet

The Serenade No. 12 for winds in C minor, K. 388/384a, was written by Wolfgang Amadeus Mozart in 1782 or 1783.

The work is sometimes called "Nachtmusik".

In 1787, Mozart transcribed the work for string quintet.

The serenade is scored for 2 oboes, 2 clarinets, 2 horns, and 2 bassoons. 

I have added 2 flutes, so it is now scored for wind dectet (decet/double wind quintet) and bass.

There are four movements:

Allegro, C minor, sonata form 

Andante, E-flat major, sonata form 

Menuet & Trio, C minor, Trio in C major, ternary form 

Allegro, C minor, ends in C major, variation form with the fifth variation (in E-flat major) augmented. 

The minuet is a canon. The oboes carry the melody with the bassoons answering one bar later. 

The trio is also canonic with the response to the melody played upside down. 

The finale is a set of variations containing a central episode in E-flat major and a coda that turns to C major near the end.
