OMelody: Thank you ...you play wonderfully... (I can
play the beginning parts of this..) This is
my favorite Chopin composition... God Bless you
for the New Year and Always... !!~!
IaxobusJames: Do not think for even a moment that you are
right in what you say. Cheers. :)
What you call mistakes, the wise call
self-expression. What? Different from common
interpretations? Even different from what Chopin
himself wrote on the page? Good. Musical
expression is not subject to mistakes (as are
hitting the right notes).
Put away your self-righteousness and your
improper judgement and fruitless criticism (and
indeed there are good forms of criticism).
Cheers :).
mozartpiano23: We need more views on Mozart requiem
karenrox4ever: Yes VERY choppy
karenrox4ever: Well done Cubus, I just think you are rushing
towards this ,as usual but i am not saying
you are bad. Everyone makes mistakes
ahpo7: A momentous rendition.
I prefer the ric CHOPIN: Waltz in A minor (Op.
Posth.) [v01]
over this version. I find the slower pace
graceful.
karliforson: I love you... sigh. 
ilovehomeschooling: Well, yes, but not as quite off beat. It is a
waltz....
Anyway, very nice. :) I do happen to prefer
version 1, though.
caeriose: my teacher is asking me to do this too. he calls
it rubato
channelhoward: ummm. this is ok i guess, but why so choppy? you
pause for one second and then play really fast.
especially in the twirl things. just sounds a
little weird. but it was played good i guess.
grab1piece: I know you did this on two version, another one
slower. I like this one much better, becaue I
feel more of the music's beuty in this one.
MaryRoseSaffron: @timothy3316
uh... vol 1 I guess
MaryRoseSaffron: good job
Volleyball1721: very excellent!!! just played it a while ago,
but your touch is great!
MoritzFaessler: very good interpretation, but i think it's all
little bit too much pedal?
dennis0mus: this kind of rubato is much much better than the
other version!!
perfect video... perfect dynamics, every note
perfectly hit! even and the color of the effect
you used matches perfectly the piece!
bye the way, what software did you use for
it?
cause I am a piano teacher and I want to use it
for my students :D
tomnguyen93: Thats how music from Romantic era is supposed
to be played :D
mamuchita18: Be Carefull with the tempo... sometimes is kind
of irregular... anyways i think is very good
 interpretation =) keep working...
