Most of all, I would like to have the capacity to play and perform the pieces of enormous technical challenges that I always aspired to such as Cziffra's transcription of Flight of The Bubble Bee and Tritsch-Tratsch Polka. Also Oscar Peterson pieces and Art Tatum's Tea for Two (which was reproduced with absolute authenticity by Yuja Wang). Also some pieces that were played by Horowitz (who I was lucky enough to meet at an autograph signing), at his famous Moscow concert. For the level I would like to achieve technically I know it would take years.... but three to obtain all of the technique necessary? Isn't that a little short? Although I do believe that mastering an instrument can be done in 8-10 years and maturing as a player.... a lifetime.
At this point in my life, I still have not achieved the dazzling technical dexterity as those who professionally perform 100% of the time for their livelihood. For a prime example of what I am looking to achieve, please reference concert pianist Kristina Miller, whose playing is absolutely astounding in both the classical and jazz idioms. According to her, the Oscar Peterson pieces she is plays were learned or reproduced from memory, not studied transcriptions, after listening to the pieces a number of times.
Sorry to hear about your injury. Your post struck a nerve with me, because although admittedly I'm much younger, I have similar ambitions as you state here, when it comes to playing Cziffra, Art Tatum, Oscar Peterson, Horowitz, etc. And yes, Kristina Miller is amazing.
"It takes one to three years to master all the technique necessary to be a virtuoso pianist.
It takes about ten thousand hours, or about eight years, to master any instrument - mastering an instrument is NOT the same as learning all the necessary technique."
Quite frankly, I find this rather idiotic -- both of the statements are really vague. What is "all the technique necessary to become a virtuosic pianist"? Tens of thousands of pianists have put in ten thousand hours, and only a handful end up being able to play pieces at the stratosphere level of technique you're talking about. This is such a ham-fisted way of looking at things, it's ridiculous. There's no room for talent, no room for personality, no room for practice methods or strategies, which quite obviously make a huge difference in outcome. Eight years to master an instrument? So can I be a violin prodigy at 8, a piano prodigy at 16, a guitar prodigy at 24 and a saxophone prodigy at 32?
I think it is possible to learn a Chopin etude in 1-3 years with a very talented student and a great teacher, and that is probably about the limit of the speed at which anyone can learn. Your average student will take probably around 10 years, though you could argue that their learning is not efficient. The pupil who can play a Cziffra or Art Tatum transcription after 3 years does not exist. Even the quickest prodigies I've seen online take at least a couple of years to get to a level where they are properly playing the Chopin etudes. And now that I'm at a level where I could probably learn a Chopin etude in a few months, let me tell you (from firsthand frustration!) that there is a massive difference in the technical skills required to play a Chopin etude, and play something insane like Art Tatum's Tiger Rag or Cziffra's Die Fladeramus transcription. There is simply no comparison. The latter may well be impossible for a majority of people due to neuroanatomical differences (though nobody knows for certain).
If you take the composite student body at the top 100 conservatoires around the world, pretty much every student has been playing the piano since they were around 5, with a good teacher, and have performed concertos, Chopin etudes etc. by the time they were 15 or so. Even after they spend several additional years at university, very few of them manage to be able to play pieces at that level of technical difficulty.
This is not to discourage you, but I'm just trying to point out what I've seen, and how ridiculous the original poster's quote is in context.
Now, getting to how to go about trying to attain that sort of technique in my personal experience so far: If you want to figure out technique really fast, you need to constantly solve new technical challenges. Challenge yourself to come up with efficient movements to be play technically difficult passages on your own. And don't wait for teachers to hand you passages that are difficult! You need to be your own teacher and have your own vision, even if you have a teacher. If the teacher knew how to make any student a virtuoso, all of their students would be virtuosos. But adult students almost never reach that level -- and it's foolish to play the same game and expect a different result.
For the very few that I've heard of who managed to become piano virtuosos as adults (and I'm talking about the Chopin etudes variety, not Cziffra transcriptions), I've observed that they have usually developed some sort of obsession, and almost in every single case have attempted difficult repertoire which was not exactly assigned to them by an instructor, and attempted to play it with dogged persistence. And it's intelligent persistence -- constantly trying to figure out the best practice strategies, movements and so on. Make sure you teach yourself really good technique. If you have tension creeping up in your hands, you're doing something wrong. And "persisting" through that tension is laziness, you need to take charge of it head on and make sure you take steps to resolve it.
Recently, a lot of really good youtube channels have come up, and you should check them out. I would suggest going through as many of the videos as you can from the following channels:
Josh Wright, Graham Fitch, cedarvillemusic, PianoCareer, Denis Zhdanov, Danae Dorken
...and there are a bunch of others. But going through a couple hundred of their videos should give you a really good idea of how things are, and how you should proceed with your studies at the piano.
Take a look at what I wrote here and the ensuing discussion:
