Has anyone used ıı book by Robert Banc'alari 'J. S. Bach for Ma

[Tenzin]

I'm just interested in if it has a range of different skill levels and how well Mr. Bandalari interprets the piees.

Any thoughts?

[Manfred Hacker]

I would say that most pieces in this book are upper intermediate to advanced. There are some shorter and easier pieces, too.
As to your second question, I am not good and knowledgeable enough to judge Mr. Bancalari's interpretation of the pieces.

I have that book and as a beginner, the pieces are pretty hard but most of them aren't crazy imo. Most of them are written without any super advanced tricky stuff.
