English: It was a good piece of etude for the training of piano techniques. It was said it came from an Etude composer named Warren Haupt ( I translated 'Haupt' into English from Chinese pronunciation, but it was almost a Germany Surname... I am sorry... ). It was said it was No.2 melody in the work Op.22. However, I still can't get any information about this melody. I guessed it was a transformed etude from other instrument, or the name of composer I had translated in a wrong way - maybe I should link the two words together, then it would be a Russian name... Oh, Sorry...

However, transcendentalist musicality taught me this manuscript can give a good training of our hands, including: 1. Dominant seventh chord arpeggio ＆ diminished seventh chord arpeggio fingering, 2. Semitone scales as linking parts threading pearls and pushing dynamics up, 3. Attached long notes keeping bass part of left hand's accompaniment, 4. Root chords (Octave) associated by pedalling creating music scenes; 5. Impression of Autumn poem describing winds sweeping fallen leaves - in imagination.

Indeed, in the ending part, my hands' controllability haven't allow me perfectly reappear sliding slurs sustaining two hands in a whole landing situation, as played by one. This point, I thought, would need more trainings. Hopefully, you can enjoy this etude of piano techniques (learn).
