FIRST PART:

Bars 1-20: First Subject in F sharp major (tonic). The first subject commences with the chord of the augmented sixth on the minor sixth of the scale. It is in two parts, Bars 1-12 and Bars 12-16. The second part is of quite a different character from the first; it is repeated, Bars 16-20.

Bars 20-22: Bars 20-22 modulate to C sharp major, the key of the following episode.

Bars 22-31: Episode. This episode is entirely constructed on one figure of two notes.

Bars 32-49: First Subject in original key. The first subject re-appears in its original key, the repetition of the second part being curtailed.

Bars 49-51: Bars 49-51 form a passage leading to the episode.

SECOND PART:

Bars 51-149: The second part commences with six bars resembling the first episode, the first of which is inverted. At Bar 57 a fresh episode is introduced, two bars in D sharp major, Bars 57-59, alternating with two bars in D sharp minor, Bars 59-61, also Bars 61-63 and 63-65. This episode eventually ends, Bar 74, on dominant seventh of C (natural) major, followed by another reference to the first episode, Bars 74-88. At Bars 89-104, the first subject re-appears in the key of B major, after which there occurs a passage leading to the repetition of Bars 51-58, slightly lengthened, with harmonic and melodic changes.

Bars 150-161: First Subject in original key.

Bars 161-End: Coda. The Coda begins with several bars (161-174) constructed upon Bar 11. After a short cadenza the movement closes with a variation (upon tonic pedal point) of the second part of the first subject.
