Anyone knows how to play Chopin Op. 10 No.7?

The Etude?

If you mean that then.....no

Its tooooooooo hard for me
I only just passed grade 5 piano (112/150) Not very high
Ikeep making unhappy smilies
Do u play the piece???
hope u learn it well

Im working on it, however, i can only reach 70% of the speed...

o well it si hard so keep trying!!

what key is it in? i can't remember which one that is off the top of my head lol...

C major.

In my opinion, it is one of the easier etudes. But it's all up to you to agree.

In the sense that there are no running notes?

Not that, once you get the fingering, just speed it up. I mean, your right hand only moves in an up and down motion. I hope you understand what I'm saying.
