There are a few piano forums around the place, PianoWorld and Piano Street being two. And there is r/piano on Reddit. I spend a lot of time on that one because I mostly read it on my phone and the other two aren’t really that friendly on a phone browser.
The thing about the online world, is you get a lot of trollery, and you get a lot of people making odd claims. Fantaisie Impromptu by Chopin is somewhat of a lightning rod for them. I started playing piano when I was 10 years old. I was not totally focussed on it in that I had school, dancing lessons, badminton, choir. My music teacher might tell you I was her best pupil ever; I’m not sure I was her most talented, but I was definitely very, very diligent. Very diligent. I mean, I practised. I tended to get distinctions in exams apart from an accident with the RIAM syllabus one year. At no point, however, were we ever going to discuss the question of Fantaisie-Impromptu or that I might approach it. I owned the sheet music of Rach 2 from the time I was 14 but that was purely indulgent on my part.
But there are a lot of threads for people who appear to be either humble-bragging, or seeking some sort of validation. Like they want to prove something or impress people. So a lot of people are “I learned this from synthasia” or “I’ve only been playing 3 years” or god forbid “3 months” and I can play Fantaisie-Impromptu”. I tend not to believe these stories but I’m interested in the context they operate in. How hard is this, if I can play this, am I able to play the hardest of Chopin’s Etudes. I have been playing 2 years and here’s my Rachmaninoff.
Or, how long will it take me to learn Ballade No 1 by Chopin, I can play Liebestraum 3 by Liszt”. It’s interesting but realistically, if you’re asking these questions, you probably can’t actually play it properly. It’s again like, people want to impress other people or themselves. They are interested in how hard it is (and therefore how proud they should be of being able to play it). But pieces come and go, I learned Fur Elise 15 years ago and I wouldn’t say I can play it now. I have to wonder, what are they trying to prove/achieve/impress? Most of these pieces are journeys and sometimes it’s not the right time to set off on them (if you have short fingers is it ever the right time for Rach?). I don’t know how many people like practising – I like being able to play pieces which is why I keep some pop repertoire on hand to play if people ask for something – but if you don’t acknowledge the effort that goes into learning pieces but are focussing on how much you can impress people by being able to knock out some hard Liszt or Ravel but then humblebrag that you started learning before breakfast…it’s a problem. In short, I see questions about difficulty coming from people claiming the kind of skills that would allow them to answer their own questions which leads me to question the claims. There are a lot of them lately.
By the way, Daniil Trifonov released a fantastic recording of the Fantaisie-Impromptu in 2017. You should check it out if you have a moment.
