I'm a classically trained musician, and used to be a free lance hornist,or French hornist ,as the instrument is called in America to avoid confusion with other instruments which are sometimes called horns,such as trumpets,trombones , clarinets ans Saxes etc.
In Europe, the term French horn is not used ,and in German speaking countries it's called just horn, and in France Cor, and Italy corno.
I don't play any more because of a physical disability, but I did a heck a lot of performing on it since I was a kid ,in countless symphony orchestras,concert bands, opera compnaies etc, and in the pit for broadway musicals etc.
I've performed in Italy,Switzerland, Australia,New Zealand,Fiji and Samoa, and many places in the US,mainly in the greater New York area.
I've had lessons on guitar,piano ,and other instruments, but the only one I was good at was the horn. I could never play the piano because I have trouble with motor co-ordination between my two hands. There are some people who are born with a deficit of this kind of co-ordination.
My classical music blog called "The Horn" is at the website blogiversity.org,which ahs blogs on a wide variety of topics,and I cover all aspects of classical music for the site. You can easily access it from the blogiversity home page, or from a link at hornmatters.com. Please try it. I hope you'll find it interesting.
