Symphony No. 37 (Haydn)

The Symphony No. 37 in C major, Hob. I/37, is a symphony by Franz Joseph Haydn. The numbering is completely misleading, as it is clearly one of Haydn's earliest symphonies. A copy of the score found at Český Krumlov, Czech Republic, is dated 1758. It can be presumed it was written for the orchestra of Count Morzin, in which Haydn was employed until February 1761.
This symphony is a candidate for the first one he ever had written, if his Symphony No. 1 was not indeed his first symphony.
Movements.
The work is scored for two oboes, bassoon, two horns, trumpets, timpani and strings with continuo. It is possible the trumpet and timpani parts were added later.
The work is in four movements:
The key organization limited to C major and C minor in the four movements indicates perhaps a reliance on the Baroque suites as a guide for tonal organization of the movements, the influence of the first three symphonies by C.P.E. Bach, or an early simplicity of tonal language. (Haydn was in his mid-20s at the composition of this symphony.)
First Movement.
Similarities have been drawn between the opening movement and the finale to Georg von Reutter's "Servizio di tavola" in C major from 1757. The two knew each other because Reutter was the director of music in St. Stephen's Cathedral where Haydn sang as a child.
Second Movement.
The work is one of the few symphonies of the Classical era to place the Minuet second (others include Haydn's 32nd and 44th, and his brother Michael's 15th and 16th). The IMSLP reverses the order of the Menuet e Trio and the Andante, thus bringing the movement order to the standard that was eventually established as common practice.
Third Movement.
The slow movement is very similar to the slow movement in one of Haydn's earliest piano sonatas, Hob. XVI:Es2.
