English: 'Chopin Impromptus Op.29' is a famous improvisation of Chopin, for 'Young Gentleman's Self-reasoning and Thinking Wandering'... Sometimes, it's also like a Fast Waltzing or Ballet or Rondo in ternary form(ABA)...

You can feel a romantic and slow stepping but deep thinking in B section... I and my student enjoy the unbalanced matching, such as 15:4 and 13:4... But, it also need a much more smooth fingering-touching way... Therefore, we are still attempting to make more exercises. You can hear my first draft. The total time is no more than 3 weeks' short teaching-training... I would improve it soon. Contrasting with Mozart, I call Chopin the 'Black-Night Prince'(It's to describe 'Contrasting to Mozart's 'Golden Prince' and its hardness for learners). Something might be from his personalities in the manuscript and the music. It's a hard life-task that I would have a short no-purpose fault-touching of keyboard in its last part , but correct it in time without breaks... I would improve it soon.

It's a good teaching practice of Sir Chopin's. Let us listen to it...
