Bernhard,
If this is the case, then what do you suggest I do to increase my piano-playing ability? I've mentioned what I hope to accomplish.... but how do I get there?
The best way (that I found so far) to develop one´s piano (and musical) ability is to learn / play pieces that fulfill two criteria:
1. It is a piece that you love.
2. It is a piece that for you, and for your present stage of development represents a challenge.
Let me expand somewhat.
1. You must love the piece in the way one loves a spouse. It cannot be a momentary lust that will survive only a one-night stand. It has to be the sort of love that will lead you to go through all sorts of drudgery and mind-numbing boredom in order to master the piece in its finest detail. In fact, the love of a spouse may not even be enough (see the number of divorces), it may have to be more like the love of a son / daughter.
This is one of the reasons technical exercises, and standard pieces one plays because one has to (the “broccoli school” of piano pedagogy: you may not like it, but it´s good for you) never works: if you don´t love the piece to bits, you will not put up with the discipline required to learn / perfect it.
2. It is very important to make a distinction between pieces that are challenging and pieces that are too difficult / impossible. Challenging pieces are the ones that you cannot play yet, but you feel that you
just could do it if you were to put the right effort and had the right instruction. They are just a little beyond you. They will take effort, but you will conquer them, and the process of doing so will be empowering and exhilarating. You will feel great not only when you master them, but during the learning stage as well. It will be like the night before Christmas. You can hardly sleep because you want to wake up and practise!
Difficult / Impossible pieces are a very different sort. You will know immediately that they are well beyond your present skills. Working on them will soon become torture. and no matter how much work you put on them you never gat any better. In fact you may observe that you are getting [i[worse[/i]. You will start avoiding them, and soon you will not even be able to hear them without all sorts of negative feelings. Moreover, you will probably develop all sorts of bad habits when working on them, and these will stay with you. It is very important to avoid difficult / impossible pieces at any point in one´s study.
However, a difficult / impossible piece does not stay like that for long. When a student first starts, Fur Elise may be completely impossible, but after 6 months – one year, it may have become just challenging. Finally it is mastered and becomes easy. The next challenging piece, may be the Moonlight´s first movement, but at this point the third movement may be completely impossible. You get the idea.
So you develop your piano playing by first of all, making a list of your favorite pieces, the ones you would love to play. Then you order them by order of difficulty, from the easiest to the most impossible. Then you just learn them in that order, so that one piece leads to the next in a sequence of ever increasing challenges. If you feel you cannot do that, ask your teacher for help (or come back here with your list).
What I am trying to get at is: Do not learn a piece simply because you believe it will be good for you. Learn it because you love it and if it is challenging, it will develop your pianistic/musical abilities. If it is easy, it will be another worthwhile addition to your repertory.
