As they are discussing this in Viva Piano, what do string-players / teachers think of the 4-year syllabus for strings? I like to buy a full set of books, partly for my own use (knowing what's there and to think about approaches to teaching the pieces, etc) and partly for forgetters-of-books, so if they turn up for a lesson without exam music a week before E-day, I can usually put my hands on a copy straight away.
I'm thankful to only have to buy a set every four years, but on the other hand, teaching them for that long is a different matter, especially when you are listening to the likes of Napoleon Crossing the Alps for the zillionth time (I'm sure most of us remember that one!)
I have exam books from the 70s and 80s, and they were 2-year syllabuses back then. Does anyone know when (or why) it changed?
