Very interesting post!
Hi I'm an advanced pianist and I'm curious about how the development of piano technique works. My personal technique is wholly derived from practicing Hanon 4 hours a day, daily. I have read many posts and articles stating that the Hanon "exercises" do not work and are not effective at developing technique. Please read my story because I'm honestly seeking answers and not argument.
I think what matters at the end of the day is acquiring the hand coordination and also the ability to do so musically. In that way, Hanon is not so different from practicing scales. The issue, I believe, is that Hanon is not that musical. Just as practicing a ton of scales should, in theory, make you able to play scales at a very fast tempo eventually, but those scales may be soul-numbingly boring to listen to. I have heard the same complaint about students who over-practice Hanon. But, practicing any physical movement regularly will improve the consistency and speed at which you can execute it.
Many years ago, when I was a child, I was mystified by the marking on my sheet music stating that Bach's prelude in c minor required a speed of 1/4 note = 144 and in another section 1/4 note = 160.
When I started playing the piano, I was amazed at the speed at which concert pianists could play passages on the piano. I figured -- if only you could learn their hand movements, you should be able to execute the same on the piano. By observation, picking up tips from pianists online, etc. I managed to learn to play at a fast tempo as well. So, there are a lot of paths to achieve the same end goal. I didn't practice Hanon at all. I believe that working on the coordination, by whatever method suits or interests you, is what is necessary at the end of the day.
When I was finished it felt like my fingers "loosened" up; I'd be playing with great agility and ease.
Yes, it's generally referred to as warming up. This is commonly observed. However, I don't think Hanon or other exercises are necessary for this. I used to do this often by improvising, playing my scales, paying attention to the finger movements, or playing through pieces in the classical repertoire. However, I don't think you should need to warm up to play pieces; if so, I think it's a sign that you're not paying enough attention to the playing mechanism and relying on chance. You should be able to play without mistakes and comfortably, cold. There is more comfort after you're warmed up, but ideally you should be able to play whatever you can when warmed up, without prior preparation. The difference should not be that large.
However one day, I tried playing the Hanon exercises at the speed that I first started to learn them, 1/4 note = 88. I noticed even greater improvement after practicing at this speed. Why?
Slow practice can be effective. Especially once you can play at a certain tempo comfortably, I find that slow practice and paying attention to comfort is what results in a lot of improvement in a lot of situations.
My routine was now 4 hours long. I would put something on television, practice Hanon, and like magic I would be able to play everything else without having to go through any of the barriers of technique that I grappled with as a teenager.
Sure, but wouldn't it be better to play anything off the bat without having to practice random exercises for 4 hours a day? Also, what level of difficulty are we talking about? Can you play through the Liszt etudes? Or Clementi sonatinas? There's a massive difference between the two. Also, how musically can you play?
My theory is that all required of piano technique is reinforcement of finger movement, which subsequently reinforces that pathways in the brain responsible for said movement. By practicing movements slowly, and CONSTANTLY, focusing on eveness of the rhythm (i.e., 'form') that brain probably does a better job and reinforcing that adeptness of the movement which then translates to being able to do that movement at very high tempos. And that's it! I honestly think it is that simple. I've read about all these other exercises, Dohnanyi, Brahms, Pischna, Czerny, etc and they all seem to focus on the same thing of 'playing a lot'. That leads me to think the only thing required to improvement piano technique is to play a lot. Does what you play matter? Your brain just needs to go through the finger movements a lot and eventually it will reinforce the coding for those movements. Is it really that simple? That's how it feels for me. I wouldn't know, because all I played was Hanon.
All that's needed to reinforce a particular set of movements is to play them a lot over a period of time, while paying attention to form. However, you will learn whatever you practice. If you practice playing mechanically, your playing will reflect that. If you develop fine touch sensitivity, your playing will reflect that, and so on. If you look at pianists' hands, you will see that all of them play somewhat differently. Why is it different? Because the small (or large) differences in approach which they, and their teachers, had, practiced and refined over thousands of hours. That's why it's important to reinforce better movements as opposed to simply relying on chance to fix technique. Of course, some people may have supremely good intuition for piano playing and not require to be taught technique at all, but they are a tiny minority.
*Edit: Again this is wholly about Piano Technique, not ear and music interpretation. Perhaps there is some relation between them, but again, I achieved my technique without mastering my ear first.
Technique, if defined as the ability to play what you can imagine or see on the page, is not distanced from musicality and the ear. This is because the physical set of motions isn't used to just "peck the keys" but also chosen deliberately to create the desired musical effect. This means that both can not be disconnected completely. What you may have done, essentially, is to learn to coordinate the different fingers in different ways at a fast tempo -- which is excellent, but not sufficient imo. However, this is all conjecture in the absence of a recording.
