I'm maybe looking for something that doesn't exist, but i have two mature adult piano students (beginners) who love jazz and would like to learn well-known jazz pieces. I've explained to them that jazz isn't easy for beginners and they're aware of that. They've both completed the Microjazz Absolute Beginners book and i've written out a couple of very easy jazz pieces with left hand just playing root notes. One of the students finds playing with both hands together incredibly difficult. I've searched for other jazz standards that would be suitable but can't find any easy enough.
I have the Piano Time Jazz book plus Jazz, Rags & Blues book 1 but i know they would struggle with them.
Is there such a thing as a book with very easy jazz pieces (preferably popular) for beginners?
