What do music specialists / peris think of it?
I am a bit puzzled that he's suggesting that Wider Ops should be offered to a KS2 class in every school, and in the next breath acknowledges that there is a dearth of specialist staff. (I guess primary teachers will be expected to add another string to their bow, so to speak. One twilight session and we'll be ready to teach violin to a bunch of thirty 8 year olds for the year!)
I was under the impression that Wider Ops virtually died a death because it was too expensive to run - we had to pay several thousand a year for our drumming tuition, and the whole class violin lessons only lasted a year.
