This explanation helps me to understand the complexity of bowed instrument playing. I grew up with a sister who practiced the violin quite a bit and it rarely sounded good to me, and I ended up playing the French horn. People speak of the horn as being very difficult to play, and we are dealing with many variables there, too, while producing a good, round tone.
There is no comparison between the two, though. The violin seems infinitely more difficult to play well.
Personally, then, I'll stick to the horn.
The only problem is that now my wife is taking up the fiddle. She is a true beginner. Here we go again. I think that she needs a private practice room away from other human ears, but I appreciate that she's giving this a try..... Her first lesson is on Monday.....
