After a few months survey on piano techniques, I have found it quite amazing that while there are a few extreme school of thoughts (finger-oriented, arm-oriented, holistic approach, for example), there are so many variations on technique concepts. Interestingly, many concepts contradict each other strongly. However, I don't think there can easily be a common agreement among experts concerning what the right techniques are.
This reminds me of a story. Two guys went travelling on the mountains by car. When they approached a stretch of road that was sided by abysses on both sides, the guy sitting o the passenger seat became quite anxious, and kept saying to the driver: “to the right! To the right!”. A moment later he would say “to the left! To the left!” after a couple of minutes of this, the driver said, quite irritated: “Will you please stop giving me contradictory instructions?”
A lot of what you see as contradictions are not really so. They appear to be contradictory partly because:
1. Language. Sometimes it is difficult to put certain instructions in words.
2. Context. Much wonderful advice in a certain context will be quite wrong in a different context.
3. “The elephant in the dark syndrome”. You may know the story of the five blind men who had never came across an elephant. When a circus came to their town they saw it as an opportunity to finally experience a real elephant. They were allowed to touch the elephant, and later on they met to talk about it. The first one said: “an elephant is like a pillar” (he had touched the leg). The second one said: “no, no, no, an elephant is like a wall!” (he had touched the body of the elephant). The third one said: “You two are crazy! An elephant is like a snake!” (he had touched the trunk). The fourth one said: “You ignorant fools! An elephant is like a large sheet of rough paper” (he had touched the ears). The fifth one said: “You are all idiots! An elephant is like a piece of curved piping!” (he had touched the tusks). There is no contradiction between the several descriptions once you realise they are all correct, but partial descriptions
4. Finally, some of the directions given by some of the forum members are simply wrong. So, of course they will contradict correct information. It is up to you to sort out the good stuff from the bad stuff.
So I'm curious to approach this issue from the other side. Eventhough no set of techniques is universally agreed as a perfect one, it might be possible to compile a list of "bad habits" that most experts agree that they should be eliminated. I searched this forum and a few other web resources, but have found that "bad habits" have been mostly mentioned without much elaboration.
Although your question is very interesting, It is important not to give too much energy to bad habits. The best way to deal with bad habits is not to fight them, but instead to replace them with good habits instead.
There is a nice line on the Iching which says some thing on the lines of:
”Do not fight evil, for to fight evil is to give it energy. Instead, make resolute progress on the way of good” Could you folks help providing your own list of "bad habits" ? At least so that they will exist here as a reference. Everyone is invited.
Here are a few (by no means exhaustive)
1. To keep practising what one already knows.
2. To play a piece from beginning to end several times (with mistakes) instead of stopping and dealing with the mistakes once and forever.
3. To work without a short/medium/long term plan.Or in other words: to jump form piece to piece without ever perfecting any. Working in such a way that the daily work does not add to anything at the end of a week/month/year.
4. To practise without a clear and specific aim for every practice session.
5. To practise mechanically (which often means unintelligently), that is, no thought is given to the possibility that the practice strategy being used may be unsuitable for the problem.
6. To practise by time rather than for results.
7. To constantly rush through pieces at top speed.
8. To try to tackle pieces that are too difficult. To try to tackle sections of a piece that are too large for a practice session. To try to learn a whole piece in ten minutes.
9. To stop practising the moment you get it right. (it is when you get it right that you should start practising!)
10. To practise mechanically without focus, concentration or mindfulness.
11. To keep changing fingerings.
12. Always starting to learn a piece from the beginning, and then never finishing it.
13. Avoiding the difficult bits of a piece and leaving them to learn/practice last.
14. practising a piece in section but not overlapping them, so that when the time comes to join the bits, ther is an inbuilt hesitation at the seams.
15. Playing only by memory.
16. Playing only by reading the music.
17. Playing only by ear.
18. Procrastinating practice.
19. Bad posture.
20. Angling the hand to help the thumb reach the keys (this puts pressure on the carpal tunnel on the outside of the wrist, and msy eventually cause carpal tunnel syndrome).
21. Misaligning the joints from the shoulder girdle down to the nail joint.
22. Breaking the nail joint (either way)
23. Using the heels of the hands to support the weight of the body on the piano (this is usually caused by having the feet tucked under the bench – another very bad habit)
24. Elbows too close to the body (they should be a fist away).
25. When the teacher requests the student to do something to answer “I can’t!” of course you can’t .We know that. If you could, you would not need to come to lessons.
26. Too much pedal.
27. Playing too loud.
28. Playing too soft.
29. Playing too near the edge of the white keys.
30. Sitting too low (if the knees are above the hip bones you are sitting too low).
31. Long nails.
32. Being late for lessons.
33. Being too early for lessons.
34. Forgetting to bring the music/assignment book for lessons.
35. Being disorganised with the music.assignment book.
36. Playing random stuff while the teacher is explaining something.
37. Believing one can cut corners.
38. Paying late.
39. Not paying.
40. Constantly arguing with the teacher instead of following instructions.
Just the tip of the iceberg.
Best wishes,
Bernhard.
