Can you name a few famous autodidacts

Welcome to the violin forum

@ think
There are some points that I see differently. The text has become very long unintentionally, which quickly looks like wild ranting on the Internet. However, I am not angry, I just want to present a neutral perspective. In short, it's just not my forte. So if something seems aggressive when in doubt, it is not intended.

I know you said that with some people money can play a role, but it sounded to me that with many you see it as a bogus argument. I would like to go into that.
It is great (without sarcasm) when you are able to take lessons, maybe even by sacrificing other things (I don't know how things are financially and for reasons of anonymity I don't even want to ask about it). But that doesn't mean that other people can set it up that way too.
Many young adults in particular cannot afford such a thing. For example, I don't know anyone in the student environment (but I don't want to rule out the possibility that they exist) who, despite a part-time job, can take lessons if this is not borne by their parents. Furthermore, if you don't have a middle-class financial background, it becomes even more difficult.
So I can also imagine that some "no longer young adults" who are not so well off, but would like to learn the violin, also have problems bearing the costs.

This argument sounds a bit like "self-taught people just don't want it enough, otherwise they would find a way to finance themselves". It may be that you didn't mean it, so I apologize for my fervor on this matter. But I've heard this argument before and it completely fails to recognize that sometimes there just aren't such opportunities, even though someone really wants them.

Of course, that's not the reason for all self-taught learners. I just wanted to make it clear that this is not just a sham reason in my opinion and I still believe that it affects quite a few.

(As an aside: I've never heard before that as an adult you have more time than children ... at least it doesn't apply to me. But that's another topic.)

Even with the argument about the fear of professional correction, I don't know how coherent this is. In my youth I had music lessons and I wasn't afraid of corrections. But that's just my personal experience.

The last thing I want to get into (also at the risk of it getting a little off-topic) and which I see very differently is your criticism of popular songs + lack of motivation. In addition, it also sounds a lot like the all too old separation between popular music (the "bad" music) and serious music (the "good" music):

I do not agree that the preference for popular pieces is due to the fact that someone is not really motivated to deal with the instrument but has taste reasons. Not everyone is interested in classical music, but the violin is. As you said yourself, an instrument is not just made for one type of music. Chalking people up because they are "only" interested in popular music, I do not think it is useful. If that's exactly what they enjoy and is precisely what allows them to express themselves, in my opinion that's completely legitimate. It is like criticizing those who practice pop singing because they do not experience the complexity of classical music, they therefore do not have such high demands on singing and their singing is lower due to their inability to sing operas (and their statement "I can sing" is therefore not to be taken as seriously as the classical singers). Many people who practice pop sing very passionately.

If the woman from the video is therefore more interested in other music, then she certainly lacks the skills you mentioned that are necessary for classical pieces. She can just play what she wants to play, that is, she can play the violin on those pieces. (At the same time, I don't even know whether she doesn't like classical music and whether she intends to play it. She's taking lessons now, so I'll just take it as a substitute for those that apply.)

It's not about how much self-taught people can achieve, but about the attitude towards self-learners themselves, that is, that you often get negative reactions just because you do it that way.

Regarding the fact that some don't want to audition at all, etc.: I don't really understand why it is so bad when someone just wants to play for themselves, i.e. why other claims should only be excuses.

To devalue a hobby because someone doesn't want to achieve the highest championship, I can't understand. Your ambition in all honor (pun not intended), because I personally share this very much, but for me that does not diminish other needs that involve less exposure. There are other hobbies that I could deepen, but which are not as important to me now as violin and I have to set my time priorities. Surely it is the same for others with their everyday life, only that the priority here is not on the violin.

Also, did it sound a bit as if this lack of aspiration is a general characteristic of self-learners? I may well get you wrong, so be sure to correct me, but the way you mentioned it sounded a bit like that.

Ok sorry for the text wall. Tldr, I'm hungry.
