1. Why 10-15 minute sessions?
In order to be successful three conditions must be met:
a. You must know what you want.
b. You must keep changing your behaviour until you get what you want (if what you are doing is not working, try something else).
c. You must have enough sensitivity to realise when you actually got what you wanted and stop trying.
(a) and (b) seem obvious enough. But what about (c)? Most people are slightly puzzled by it. “Sure I will know when I got what I wanted!”
So I will give you an example. Years ago, I was very much into magic tricks and juggling. I had a friend who was also into these things. We were asked to go to a children’s party and entertain the children, which we gladly did. On arrival, it turned up that the children were quite a boisterous and rowdy group. They were climbing on top of each other to get to the juggling clubs and balls and having a grand old time by mocking about and being overexcited. We had prepared a number of routines, but it was clear that under the circumstances, it was not going to happen. My friend was very distressed. I had to tell him: “Look, what is our goals here? To show off? No, we are here to entertain the children. They could not be more entertained!”. With this he relaxed and we just had a good time. You wee, sometimes you are already getting what you wanted in the first place but
you do not notice.
Here is another story. Once upon a time an encyclopaedia salesman tried to sell me an encyclopaedia. I was not particularly interested to start with, but as he started to talk, he completely convinced me that buying an encyclopaedia from him was the key to my eternal happiness. He was good. He had a superb patter. But
he did not know when to stop. As I was ready to sign a cheque, he just kept going on and on, even though his goal had already been accomplished. This gave me the opportunity to think things over, and I ended up not buying the encyclopaedia.
Many piano students are like that. They don’t know when to stop. They will go on practising the same passage day after day for hours on end. You also have the opposite kind of student, the ones that stop as soon as they barely got the passage together.
Anyone should be able to master any passage in 10 –15 minutes. There is nothing magical about the time. Make it 20 minutes if you prefer.
There is no need for more, and no further benefit will accrue from more practice than that on a single day.
Of course, there are exceptions. If you are going to practice your performance of the Hammerklavier, this is going to take 40 – 50- minutes. If you are using some particularly lengthy practice tricks like repeated note groups, this is going to take 30 – 45 minutes. But practising a passage for 4 – 5 hours, when you already mastered it after 15 minutes is simply lack of sensitivity in perceiving that you have already achieved your goal.
2. Say you are working on only 5 pieces, could you plan 2 consecutive 10-15 minute sessions in one day with the same piece; 8 bars instead of just 4 for example? If not, why?
Yes, that is exactly what you should do. Instead of working 4 hours on a passage, you should divide these 4 hours into 12 sessions of 15 minutes (with 5 minutes rest in between) and work on twelve different sections (either of the same piece or of different pieces).
3. How about time crunches and dead lines? I know that these probably fall somewhere under middle term, but what if you need to learn a new piece for something, quickly, that you did not plan on learning that month (or year)? Would you do that practice separately and otherwise sitck to your schedule?
Deadlines are emergencies. Then of course your usual schedule go through the window. Which is one of the reasons that you should avoid them. Always say no to proposals that will generate deadlines and the resulting stress.
4. Are you suggesting that one uses the beginning sessions of practicing a new piece just listening and breaking learning sessions down, or is that separate work done in preparation for practice at the piano?
You can use your practising sessions for anything that you want, from learning a piece from scratch to polishing a piece. But is must be well planned (in the short term, middle term and long term) and consistency is the key.
5. In getting to know this routine, how can one plan a solo concert without knowing exactly how long it may take one to learn an entire program (one may have calculated 6 mos total, but perhaps there is need of recalculation 3 months into it)?
As the years go by and experience increases, you will be able to tell what you will be able to accomplish and how long it will take you. In any case you should always plan for the unexpected. Above all do not accept proposals if you think you may just make it. Some people work well under pressure, I am not one of them. I was once approached by a violinist who wanted to play the Franck Sonata. His normal accompanist had had a serious car accident and there was no way he would recover in time. Although I knew the violinist and was very sympathetic towards his problem, and although I wanted to help, I also knew that in order to have the piece ready in the time suggested, I would pretty much have to stop everything I was doing, and probably the piece would not be at its best. Plus the stress would work against me. So I declined, because had I accepted I would probably do this guy a disservice.
Finally, I have explained most of this subject in much greater detail here:
