I'm still kicking myself that I never followed up on the violin lessons I took for a year when I was 4. I'm dying to learn a better melody instrument (Heaven help me, I love the lap dulcimer but it's a pain in the neck to play in a group, outdoors, in a noisy room, when amplified, etc. etc.). And hammered dulcimers aren't portable enough--I hate tuning all the time and they have SO many strings.I'd love to be able to play the guitar well, too. And, yeah, the dobro. And banjo.
But mostly, I dream of fiddles.
