Hi Saxwarbler!! Sounds like a good challenge! How did you get on in the end with Angelic Harmony? I still really love it - beautiful piece - and many of the other studies in that book are goo dto play too, so value for money!
I gave it a good go but am putting it on hold whilst I try out a few other pieces. I'm about to make a start on Polnisches Lied and I think the B piece will be one of these two, with maybe Tom Bowling in reserve, although I haven't really had a good look at the latter yet.
