More and more, from Ted Lehmann’s experience, roots musicians are coming to the scene with more classical training. It would be common, 25 years ago, for roots musicians to be unable to read music, Lehmann said. When he got his start blogging about and photographing musicians in 2003 — Lehmann considers himself a “newbie” — things were changing, but slowly. “You’d ask them that question [about being able to read music] and they’d say, ‘Well, a little bit, but not enough to hurt me,’” he said. “In other words, ‘I’m not going to lose my improvisational awareness.’”
