Piano Etude Op. 25 No. 11 in A minor, also known as the 'Winter Wind', is a solo piano work composed by Fryderyk (Frederic) Chopin in 1836. The Winter Wind is an piano etude for developing stamina, dexterity, and technique - essential skills for any concert pianist.
As an piano etude stands, the Winter Wind etude is an epic study of right hand dexterity and left hand flexibility. Both hands play an important role throughout the piece; the melody is sung through the heavy left hand, and the right hand contributes the etude's namesake with rapid scales and arpeggios. This study must be navigated with polyphonic mindset, treating both hands as separate melodies that work together, in a duet for one performer.
Piano Etude Op. 25 No. 12 in C minor is the last of Frederic Chopin's formal studies for the piano, opus 25, dedicated to Madame the Countess d'Agoult.
This piano etude, also known as the "Ocean", is a series of rising and falling arpeggios in various Chord progressions from C minor. In addition, its opening bars recall the chord structure of the opening bars of the second prelude of the first book of the Well-Tempered Clavier.
