I'm an English teacher, trombonist, and amateur brass tech in Central Washington. I started playing harmonica when I was 6, but quit in my teens. Tried to take that next step to chromatic, got spooked, and gave up. Recently, I've found myself in a bar band, and I've realized that there aren't a lot of trombone parts in country-western music, so I'm re-learning the harp. I'm getting better at cross-harp and note bending, but my technique needs a lot of work. Anyhow, that's me. I appreciate the community here. I've already received a couple of very helpful answers.
Your musical back ground will help you get back into the swing of things, especially knowing how important a proper embouchure is.
As for country music, listening to Mickey Rafael harpist for Willie Nelson's band help me a lot, that, and country scales.
Man-O-Man, Man, I wish I had a 'Bone player in my band.
