I have a retired lady who is nearing the end of Dozen A Day Book 2 (green) and finding it difficult. She managed not too badly with the blue book, but this one has been a struggle and progress has been very, very slow. Book 3 is out of the question as it would be far too complicated.
I've been looking online at piano study books this morning, but haven't found anything that would be suitable. I'm looking for something of a level between Dozen A Day books 1 and 2. She enjoys short studies of maybe 4 - 8 bars long, and they'd need to be pretty easy.
Any suggestions please?
