Seriously though, learning to play any acoustic instrument is like learning to drive. You don't just jump into a racecar on your first lesson. You start slow. You get some help along the way if you need it, but generally you learn by doing. Driving becomes second nature from experience. So much so that a few years down the road it's almost automatic. You don't think about shifting or changing pedals, you just do it. Which (I promise) is exactly how fiddling is. Sure, it starts out squeaky and lame, but you get better. Things start to become comfortable. And before you know what hit you - you're practicing for an open mic night with your first band. Which is what I was doing last night. The reality of that still shocks me, and I've been playing for years now.
So like I said, I'm not special, I just made it a point to practice everyday. I was also lucky to come across the right beginner's books that made teaching myself easy. Those "Ignoramus" books by Wayne Erbsen of nativeground.com are pure gold when it comes to self-instruction. If you pick up his old-time fiddle book and a cheap violin, you're set. You'll be playing by the campfire come June if you're willing to practice. Really. He also sells banjo (bluegrass and clawhammer) and mandolin ignoramus books as well.
The point of mountain music is enjoying it. I think a lot of recreational fiddlers and banjo players feel the same way. We're not in this game to win prizes or be the best - we're in it to keep a tradition alive and entertain ourselves while doing so. Personally, I'm also in it for the community. Pickers, pluckers, and strummers are some of the happiest, most laid-back, and interesting people I've ever had the pleasure to meet. Because of my dulcimer, fiddle and banjo I've been put in situations where new people and new experiences are always popping up. jams, festivals, lessons, campfires - thanks to music I get out there and learn people's names. Something that isn't always easy to do when your road has more horses than humans. I am even considering going to a banjo camp for a weekend this summer. You just don't get these kind of experiences when you take up scrimshaw.
So folks, if you want to learn, learn. You need no one's permission but your own. Start cheap and slow, and build on it if it makes you happy. Which, and I'm talking from direct experience here, it certainly will. See ya at the next jam, son.
