Moscheles, Mendelssohn's teacher and friend. Composed at the recommendation of Moscheles. It is included in 'Méthode des méthodes', a pedagogical work co-published by Moscheles and musicologist Fétis.

Presto agitato, 4/4 time. A rich, powerful melody is played in the soprano voice, while arpeggiated accompaniment is distributed between both hands. While it is essential to bring out the melody lyrically, the piece should be performed musically, paying attention to the bass line's movement and perceiving the sonic variations produced by the arpeggios.
