Key: G major

Tempo: Andante

Time Signature: 2/4

This movement is the second in Haydn's Symphony 101 in D major, sometimes called The Clock because of the nature of the second movement.

Symphony 101 in D major was written as one of Haydn's London symphonies, written between 1793 and 1794.

This slow movement is in G major. The moving quavers in the major sections are what gives this symphony its name. Towards the middle of the movement, there is a dark passage in G minor, followed by the clock theme once again.

The clarinet parts are notated in the key of B♭ major (a minor third higher) while the horns and trumpets become horns in G and trumpets in C respectively. This means that the music notated for the clarinets will sound a minor third lower than written. The horns will sound a perfect fourth lower than written, while the trumpets sound as written. The name for instruments that sound differently to how they are written is transposing instruments.

The overall form of the movement revolves around the two main musical sections, starting in bars 1 and 12 respectively. These sections are repeated throughout the piece with slight alterations.

The instrumentation for this movement is similar to the traditional orchestra during the Classical period. The instruments used include: a string section, 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets and 2 timpani (tuned to tonic and dominant).
