Just back from a week away with the quartet. I decided this would be the week I looked at alto clef with some real determination.
I had about 30 mins looking at it, and trying to sight read on my 5-string and then the next session I was playing viola for real

. Tryzard1's viola is a bit bigger than my 5-string (which is a violin with an extra c string), and heavier, and gutsier

of course.
Anyway it was OK, and although I now have shoulder ache

(I think his shoulder rest set up was not ideal for me), I think it looks like I have in fact succumbed to the viola-bug.
You knew it was just a matter of time
