This movement is in rondo form which can be represented formally by the letters ABACA - a rondo is a piece with a recurring theme having its origins as a dance.Changing the finger on a repeating note is a piano technique that can be usefully explored in this movement if only to give to a lightness to the touch which is required if the movement is to be played at tempo. In fast playing the dynamics also need to be controlled and I would avoid playing the movement too loudly. A performance tempo of 100 quarter note beats to the minute is a good first target. The realisation playback tempo is 144 quarter note (crotchet) beats to the minute with the repeats for a change played in the realisation. Ornaments and appoggiaturas are written out in the edited music score with trills beginning on the note. Understand that there are several options and solutions available as far as "suggested" fingering is concerned but it is a work in which legato, staccato and staccatissimo touches can be explored. In the repeats gifted and sensitive interpreters of Haydn's music add additional ornaments and figurations whilst possibly varying the dynamic and tempo but all keeping to the musical style. This is an excellent piece for developing musical memory and when possible players should try and put the sheet music aside. The movement composed in the late 1770's has more than a suggestion of the spirit of the composer and his evident humour. A plain score is also appended to the edited sheet music score allowing the player some flexibility in their approach.
