F major, 4/4 time. Following Nos. 21 and 26, this piece is untitled. It begins with the indication 'molto lento' (very slowly), and other tempo markings are also found throughout the piece. Regarding the repetition of the opening eight measures, the first time should be played p (piano) and the second time pp (pianissimo). In the sketch stage, it was in C major. Since it is written in four voices, it is necessary to play while being aware of the role of each voice.
