The third and last of the three Bagatelles begins with sharp staccatissimo phrases on the ‘cello, answered by short, descending runs on the piano. As they exchange motifs, the piano eventually takes up the rapid, staccato phrases leading to a more expansive section, with the ‘cello’s strident line playing out against block chords from the piano. The piano responds with a quieter presentation of the same material before the troubled staccato mood returns rising to high, extended climax on the ‘cello. The movement then recalls themes and passages from the two previous Bagatelles, weaving them together to bring the third Bagatelle to a furious conclusion.
