What do teachers think of the new pieces? I've only seen the new Gr2 violin pieces and on first glace they seem a bit hard especially List B with 2 pieces with 2 flats. It is a huge jump from Gr1 especially for younger kids or slower kids. I have been working on a few pieces from Gr4 (but not from the actual book yet) and they seem easier than last year. What have others found???
