It is presumed that this music was composed with Nikolaus Esterházy in mind, tailored to his preferences. Alongside Haydn's characteristic optimistic side, beautifully flowing melodies are also written, depicting Haydn's delicate aspect. The atmosphere of this first movement changes considerably depending on the tempo. Although it is Allegro moderato, if it is too slow, the sense of liveliness will be lost. The piece is by no means heavy; therefore, please start it lively and lightly. Broken octaves appear in this first movement (left hand from measure 14 onwards). The atmosphere of this first movement changes considerably depending on whether these octaves are played legato or dryly. These broken octaves in the left hand are also written in the section leading to the peak point of the development; if the left hand is played legato here, it feels as though the tension and the sense of direction towards the peak point would be lost. While the author's personal preference is to play them dryly, ultimately, it is left to the performer.
