problems about new pieces and psychological aspects in my head

[rachmforever]

Hey guys.
Since last week I have really troubles to learn something new. My teacher said to me I should choose some new repertoire. First I wanted play some Chopin so I tried 3th Sonata -> failed with memory, next Fantasy F minor -> failed after 4 pages ( maybe i was just lazy to practice enough this ) same with Scherzo B minor. Second I should choose some sonata I played Beethoven's sonatas before So I really wanted play some romantic or 20/21 century. I tried Liszt sonata b minor after 8-10 pages I failed lol nothing new now! It was probably cuz hard technical places I was lazy to practice them or they was just too hard for me. as I have mentioned 3th sonata Chopin-> NO... Next I tried Scriabin first sonata F minor . No way to memorize this piece it's quite new world for me.
Yes I think All people have bad piano days I have them too but not so long it's more than weekend now and I feel pretty upset on myself and on world it making me more edgy. I think I should be able play this pieces cuz I played harder in past. I didn't tell about this problem to my teacher yet because I'm really shame for this.
I would be glad for some advices about psychic page or some tips of pieces or anything what can help me.
Anyway thanks and Sorry for my English I know it's not the best..

You think you should be able to play these pieces: maybe you are expecting to learn them too fast. It seems that you launch into a piece but give up on it quickly if you can't master it or memorise it almost straightaway.

Each new piece is a new world. Take it slowly, be patient. Spend time on details, trying out different fingering, looking for the most efficient way to play a particular passage. A new piece is a wonderful opportunity to make a fresh start without being hampered by bad technical habits from pieces that you have been playing for a long time.

Are you by any chance obsessed by playing long and difficult pieces? And then feel a failure if you
stumble in the first couple of pages ? Been there, done that.... Yes maybe you "should" be able to play them based on previous repertoire. But life is not all about playing increasingly harder pieces. By all means take a step back now and then, several steps even. Take a simple and technically easy piece and concentrate on the musical rather than technical challenges. It is very refreshing, relaxing and motivating, and will work wonders for your technique and touch. At least this was
my experience.

What criteria are you using to select your pieces?  You love to listen to them?  Everyone says that these are impressive in performance?  Personally, since I'm going to live with a piece for a while, I try to select pieces which are challenging, but to which I enjoy listening.

Also, what else are your working on?  Right now, I'm working on a one Mozart sonata and three shorter pieces by Bach and Chopin.  I find if I can work on pieces of different lengths, my practicing is more enjoyable.

The road to "done" on a piece is a long one, so if you're already playing long pieces, why not chose some short ones you'd enjoy.

You say you are failing to learn these pieces.  How exactly are you defining the word fail?  What do you think you are doing or not doing such that you have deemed them a failure?  What expectations are you setting for yourself in order to deem a piece a success?
