Learn to play piano / keyboard with Filo & Pastry Amazon.com 5 star *****
I really like this book, it's very informative and even though it is made for kids (and very silly adults) it has a lot of information. It is definitely helping me learn the piano, I am using another book as well but what that one doesn't tell me this one does. I had problems with the pdf download (pictures were too small on my kindle) and when I emailed support they got right back to me and solved my problem immediately! Will definitely check out this authors other works.
Lovely book , well packed , very pleased -
