I keep getting frustrated and a lot of time lack the motivation. I have been working it either a measure at a time or a phrase. Separate hands slowly, with a metronome, and put it together slowly...so I just move on to playing something else or leave the piano entirely for the time.
You've got to lower your ambitions even more. The most important motivation engine is the feeling of making progress - no matter how small. Try to analyze your difficulties even deeper than before: is your problem really a whole bar? To me, it is often just one little movement, one transition, that makes the whole "problem". And so I end up playing just two or three notes in a sequence, over and over and over and over again. Ta-dah-dah, ta-dah-dah, ta-dah-dah. Quick and slow. Sometimes the keystrokes have to be doubled or tripled, or been played punctuated and in other versions, in order to keep your brain "active". And when you feel you make something better than before, you must give this attention and give yourself a little mental reward. The usual problem is that we ignore little progress because we focus on bigger ones, and hence we get disencouraged and hence we lose our temper, get frustrated and BLOCK ourselves. Compare this with a dog that you train - if you demand too much from him at a time, it will be too difficult for him, he won't get the reward when he needs it, and so he will lose motivation and walk away. You are not different from the dog, you need to get encouraged as well.... and if you find this slow, baby-step way of working just too frustrating because you get impatient, you must play pieces that are more easy. Personally I don't see the point in playing things I don't want to play, in order to learn how to learn things I really want to play, instead of working more with things I want to play ... but that's me. I can accept that it takes forever to learn some things ...
I`ve seen in this Forum many members who say that they dont love Bach or that Bach is hard to memorise and to play without mistakes.No one is obliged to love Bach. But Bach is simply wonderful when we understand his music and Bach techniques of composition. Only one example: In two voices Invention no 1, at the beginning, there are 3 bars where Bach presents simultaneously the theme, its reverse and itts mirror! And we may choose what we want to ear. Invention no 1 is quite easy, no one presents it in public. Nevertheless, those 3 bars are a delightfull "perl" of composition. When one understands Bach, one loves Bach.Another problen is how memorise. Since my beggining, when I was a kid, I allways "study" Bach bar by bar or phrase by phrase, hands separated and accordingly the "aditif method": one bar, then the other, then de 1º and 2º bars, than the 3º, then the 1º,2º and third... and I repeat each bar "y" times, untill it becomes perfect. OK, this takes time, indeed. But tihs method works. You may wish to try it.Good luckrui
I prefer to learn by phrases or musical ideas. That's what my piano professor taught me and it seemed to work then. Anyhow, what I would like is a goal to work on it for so long each day. I think that might help. Starting small.And then to take it really slow with a metronome and speed it back up.
