Thanks again for your advice and compliment. I also enjoyed listening your Mozart

I studied piano since 5 for more than 17 years.
After that, I'm a self learner, so I'm free to choose whatever piece I wanted to learn.
Piano wasn't my 1st life until about 6 months ago. Now I'm fully teaching piano.
I start learned Heroic some years ago for abt 3 weeks (only learn), then play/polish it on and off (abt 10% on, 90% off) until now.
As for impromptu, I learned it abt 7 months ago for about 1 week (only learn) then ... yes, played it on and off .
During off period, I learn or polish another pieces.
Play Heroic and this impromptu is completely different things.
To play Heroic, we have to coordinate the whole part of our body very well , keep everything "linear" and efficient. Also need a well trained relaxation technique while playing as well as endurance.
But for finger work, I personally think this Schubert impromptu is need more carefulness for each note.
If you want advice from me to learn Heroic, never2 be scared with any piece. But keep everything well programmed and prepared. So first you have to know what is needed there.
By the way piano121, get back to the topic, since you also learning this piece, would highly appreciate if you have time to hear my earlier recording of this piece. At the beginning it less evenness and not so smooth, but as a whole, I begin to think it's more lively and more connected each of the section. Also mistakes are not so disturbing.
But what do you think?
