I agree mostly with Boo. I'm not remotely interested in violin and am itching to get started on viola. It has nothing to do with being useless at more popular instruments, because I have an odd personality or because I want to make it in an orchetra. It's simply because I like it better. I like the lower tones better than the higher ones and, given the enormous popularity of cello music and how many violin players go on to play cello and viola, I would say I'm by no means alone. Many viola and cello players come from violin, but it's interesting that few violin players come from cello or viola. Maybe they struck gold first time?

That bit where someone said 'I'd rather not say what personalities go for viola as it might offend' (or something like that) made it sound distinctly as if viola players are natural throw-backs or something!
A lot of the problem is in people's minds, not in the instrument or what people who play it are really like. I daresay that many who've gone on to viola from not enjoying violin have often said what was expected of them as well as violists are simply assumed to be failed, or bored, violinists. When I asked for tips on starting viola I was immediately answered as if I played violin! Pre-conceptions and popular mythology is rarely helpful!
I think a lot of people simply don't
know viola and, when they hear it, they like it well enough. Many people also don't know what certain woodwind of brass instruments are because everyone focuses on violin, cello, guitar, flute, clarinet, trumpet and piano. Lots of folk don't know oboe, piccolo, French horn, bassoon, bass clarinet etc etc. From what I can see though, viola seems to be becoming an increasingly trendy instrument. Not that that's why I'm interested in it though - I don't like most of the recent music writeen for it, it's all drama and noise, but one hopes things will improve at some point!!
IMHO, viola player jokes aren't any more funny than any other type of 'humour' that picks on one group of people without any real cause and makes them the butt of stupid comments whilst expecting them to 'take it well' and even to find it funny themselves! It would be a different story if jokes started to circulate about violinists, or pianists, or flautists, or..... Now
they wouldn't be funny, would they?
