study piano

[poernomo]

I'd worked with more pieces piano like :  
1. Chopin Etude op 10 no. 1  and 12
2. Moszkowski op. 72
3. Book Russian Technical Regimen ( Alexander Peskanov ) include Double note , broken Chord, Arpeggio
4. Czerny op. 740
5. Burgmuller op. 109  
6. Heller op 45
7. Short  prelude and Fugure – JS Bach

for a while book burgmuller and JS Bach will finished . I confuse which piano books that useful for developing my skill in piano. I have read the best book Scarlatti sonatas for delevopment technique in piano forum , but it is the same with Czerny op. 740. If  i was studying this book, doesn’t it wasting time ? Every day, I practiced  to develop the  piano techinque  ( Chopin Etude, Moskowski, Alexander Peskanov and Czerny ) for 3 Hours.
I really confuse with what i have worked.  
I really thankfully, if there is someone could give  any  suggestion to me ?.  

Thanks,

Practicing Czerny is great if all you want to do is play Czerny.  But who does that?  The purpose of Czerny is supposed to help you with playing Beethoven but look at all the studies in Op. 740 or 299 etc.!  If you spent all your time practicing studies, you'll never have the time to practice actual repetory.

Studies, like Czerny, are a good tool if:
1.  You are having difficulty on the piece you are working on
2. The study is to help with the technical difficulty in the current piece you are working on.

But what if the piece you are working present you with no difficulty at all?  Then what is the point of using these exercises?  None.  If you do not have any technical difficulties in a piece, then there is no need to utilize a technical exercise.

If you spent those 3 hours on actual repetory, and there are difficulties that your technique will not help with, then perhaps you can look for the execise that may help alleviate that difficulty.

And what if the technical exercises you do present no difficulty at all to you?  And you still practice them.  Then doesn't that mean that you do not have the technical difficulty presented in those exercises?  And isn't that a waste of time?  The technical exercises that are a problem for you to play are the ones that you should be working on if it relates to a piece you are currently working on.

Thanks faulty_damper for the replies. I agree with you for spent those 3 hours on actual repetory and practice specific technical exercises or etude practice which addresses particular problems found in current works being studied. I was studied czerny, moszkowski and chopin but not at all, I  practice specified for left hand exercise. Chopin is said to have studied and taught these rather gymnastic pieces, which focus on strength, agility and caprice. I read this in  https://pianoeducation.org/pnotmi3.html
What must I do to choose actual repetory that could develop my skill in piano (all) like chopin, but that enjoy for other person/ Concert?
Do you have any suggestion which repetory I must studied ?

Thanks

It's useless to have the ability to play every single repetory that was ever written if you are never going to use those skills.  If you prefer Chopin, then you should choose those exercises that would help you play Chopin.  Don't attempt to learn exercises when you have not even attempted to play the piece.  I'm confused.  This isn't what you are asking.  You are asking which pieces in repetory would help you develop the skills to tackle most pieces?

I don't think there are any pieces that deal with all technical issues in all of the repetory.  But, there aren't very many technical difficulties that exist in piano playing - there really isn't that many as those exercises would suggest.

For your own pleasure, just pick the repetory that you like and want to play and deal with the technical difficulties in those pieces if they are present.  If you don't think the pieces are that difficult, then choose something else that you like and want to play.

For me, I do just what I suggested: play the repetory that I like and want to play.  I'm currently working on Alkan's Symphony for solo piano (Op. 39-4).  The main difficulty in Alkan's works seem to be quick chord progressions.  Since I haven't had any practice on chord progressions, playing Alkan is a good way to deal with them.  His Opus 39 was composed as Etudes so that pretty much eliminates the use of outside studies to play this study.  And the best part is that it sounds great!
