Question about adult beginner progression
This is gonna be a question mostly for teachers but if anyone has any other input I'm totally coolio with that. I started piano beginning of this year and am pretty motivated to improve, I clock in at least an hour a day and really enjoy it. I do have a classically trained teacher going through the classical methods and am steadily improving.
My main question to teachers is, has any teachers actually seen an adult beginner become a virtuoso? This question is really important to me because I am an adult in my mid 20s and piano is quickly becoming a big part of my life and I have pretty steep aspirations, various Chopin and Liszt etudes to be exact. I'm sure its astronomically rare but if there's even one example out there It would potentially remove any mental block in the future, similar to how as soon as one person breaks the 4 minute mile, immediately after many others broke it and I'm just genuinely curious.
I have tried to find any example but the extreme techniques required for some lizst pieces are seemingly the barrier that prevents a lot of adults from becoming a true virtuose. By extreme techniques I mean rapid lizst style octaves, repeated single notes that jump wildly, wide jumps, 45 trills that you see in many of his etudes. This is as opposed to something like revolutionary etude, a piece you could decently get down just through pure muscle memory on synthesia. Could it be not starting younger makes it impossibly difficult to achieve?
The reason I want this answered from teachers specifically because of course you have your youtuber synthesia superstar prodigy that's learned fantasie impromptu in 1 year, but I'm sure I don't have to explain why I don't want to learn that way. Teachers also have the most amount of data on piano learners and have a general idea of what's normal and not.
My teachers perspective: He doesn't think its realistically possible for most adults, mostly due to time constraints and potential fine motor function loss from not starting earlier. He has stated he thinks its possible for me but will require immense dedication and a minimum 2 hours a day but it's simply too early to tell and I just have to put the work in. An example of a technique that's hard, trills. He has stated that trills is a MAJOR technical barrier for many people just due to weak starting fine motor skills and to play something like 45 trills on la campanella would be a near impossible task for an adult not extraordinarily gifted in the trills department.
anyways, would appreciate any input, thanks.
