Étude Op. 25, No. 9 (Chopin)

"[1] The composition is a study of staccato – marcato alternations, marked throughout the piece.

The piece is marked Allegro assai and is written in 24 meter.

It is the shortest of Chopin's études, lasting under a minute played at the indicated tempo.

This makes a four-note group, the structure of which is used during the whole piece to convey the melody.

The structure of rapid octaves can pose a challenge to the less technically experienced.
