We are talking here about two schools of thought; two different philosophies. At some stage you will have to choose.
Your teacher is absolutely correct when he says that:
He told me that in order to get technique from pieces you should not practice them enterily
You will not get any technique from pieces by just playing them. You need to have a specific program for work on your pieces so as to develop your technique
in order to play them.
However there is a huge flaw in what he says next. (according to the school of thought I subscribe to, and to this day I have not yet seen any good argument against it – the reason I subscribe to it in the first place). The huge flaw is this: That technique can be dissociated from musical purpose and meaning.
Yes, Czerny studies are derived from the difficult bars in Beethoven sonatas (for instance). However, the musical purpose and meaning of the fast arpeggios in the 3rd movement of the Moonlight is very different from the musical meaning and purpose (if you can find any) on Czerny’s op. 299 no. 3, which superficially would seem to deal with the same technique. You can practice the Czerny as much as you want, but the technique you will be acquiring will not be the technique you will need for the Beethoven.
You will have to change it completely and modify it to suit the musical purposes of Beethoven.
Hanon is also derived from patterns found in the repertory (most notably Bach). Take his repeated note exercise no. 47. Surely repeated notes can be best learned in isolation and then applied to whatever piece they appear? Surely this will save time? Well, think again. Are you going to change fingers in the repeated notes? That is one technique. Are you going to play the repeated notes with the same finger? That is another technique. Which finger(s) are you actually going to use? Are you going to accent some of the notes? Are you going to play them evenly? Are you going to articulate them the same?
You see, these decisions cannot possibly be taken if you are doing Hanon, Czerny, Pischna and the like. They are not musically sophisticated enough.
The repeated notes in the LH of Beethoven’s Fur Elise require a different technique from the repeated notes in Scarlatti’s K141 and from Chopin’s prelude op. 28 no. 15. Each of these pieces will require a careful study in order to decide issues of tempo, agogics, articulation, rhythms (harmonic, metric, melodic, etc.) plus intended incongruities between metrical and musical aspects, your own body responses to the overall rhythmic pattern of the piece/passage, accents, etc.
You will never get the technique – which by now you may start to realise is completely specific to the piece you are playing – to play either Beethoven, or Scarlatti, or Chopin repeated notes from Hanon or Czerny. In fact the only technique you will get from Czerny is the technique necessary to play Czerny.
Now if you believe in the other school of thought (technique can be separated from music, can be learned on its own and basically is the same no matter what the piece is), then of course you should do as much Czerny (and yes, Hanon as well) as you can possibly get your hands on. In fact you should delay working on repertory and only tackle any piece after 5 years working on pure technique (there are people who actually propose such insanity – the most notorious being no other than old Rach himself)
However, if like me you belong to the school of thought that believes that technique is dictated by musical content, then the only reason to play Czerny, is if you actually want to play it. There is nothing wrong with that. He did write some pretty pieces (even some pretty studies). So of course, if you want to include some of Czerny’s pieces in your repertory, and play them as encores or for your own pleasure, then work on them.
But if you are playing them in the hope that you are saving time by learning with Czerny a technique that you will then be able to apply to repertory, think again.
The piano repertory is huge. There are more pieces written for piano than for all other instruments combined. I will never be able to play everything I want to play. One lifetime is simply not enough. I for one have no intention of touching any piece that I have no interest in playing.
I understand, of course that you are in a school which may have demands and philosophies other than the ones I subscribe to. So you will just have to put up with it and make the best of it.
You must also understand this:
Never start from generalities (As someone recently posted: “My teacher told me to use Hanon and to believe him”). Always start from problems. Real, specific problems. If a teacher wants his student to use Hanon, that is fine as long as there is a real, specific problem to be solved. A student should ask the teacher bluntly and directly – and of course politely: “Which specific problem will I solve by doing this exercise?”. Good answer: “That run in bars 122 – 125 of the Mozart sonata is terribly uneven and muddled – I believe that working on Hanon no. 14 for 15 minutes every day will solve the problem in a week or so” is a very good answer, and I would urge you to follow your teacher’s advice – if anything to see if it actually works.
Completely wrong answer: “You must do Hanon every day for one hour to warm-up and because it will develop your general technique. Just trust me”. The teacher (and this realisation always comes as a shock) may even be a great concert pianist, he may even be Russian, but he is ignorant of the issues involved and does not know what he is talking about. Worse, he did not go to the trouble of informing himself since most of this information is now freely available.
According to him by only practicing pieces you need more time to eventually learn them because you lack the technique to play them and you get the technique by practicing them, only that in a 10 pages long only few bars contain technique challenges
On the other hand if you practice on Czerny or Pozzoli in each study there are different technique challenges so that when you eventually have learned them and start practicing Nocturnes, Sonatas, Preludes and so on you already have much if not all the techcnique needed to play these pieces and you don't have to waste your time trying to acquire technique on all the repetitive pattern and easy bars of a long sonata
Again, I cannot really see the sense in this. If most of the bars of a sonata are easy and repetitive, why should you need to do exercises to acquire the technique to play them? And if you do not have the technique to play the easy repetitive patterns in a sonata, surely the best way to acquire the technique to play them is by working on them, and attending to their specific musical requirements –not in an exercise whose musical requirements are completely unrelated.
Finally,once you acquire a technique it is yours for life. You do not need to keep working on it. I did Hanon on my youth. I haven’t touched it for several decades. I can still do all of them perfectly and from memory (which just shows how technically undemanding they actually are).
I hear of people spending two three hours every day “working on technique”. I truly do not understand this. Do they work at “walking”, do they work at “lifting a fork to their mouths” just in case they blotch the technique and cannot feed themselves ever again? I lived in Japan for a while, and I learned (with perfect technique) to eat with chopsticks. Do I practise it everyday? Of course not. I have not eaten with chopsticks now for may years. Yet on the odd occasion when I go to a Chinese or Japanese restaurant I can still impress my companions with my perfect technique.
The problem of course, is that most people never acquire the technique in the first place. They fool themselves that they do. They may even “practise” it hours on end. And yet you can always see them in Chinese restaurants holding the chopsticks in the wrong way and dropping food in their laps.
So it is with piano. You may spend tens of hours at the piano for several years and yet not acquire any technique. Or you can acquire all the technique you ever need in no time at all (my reckoning at this point in my life is one – two years, but I am always on the look out for ways to shorten this time). It all hinges on if you know what you are doing.
Best wishes,
