Learning Scales- Visual Guide by Ellie Hallett
h ttps://pianoscales.com.au/ I would highly recommend this book: Learning to play hands together scales accurately has never been easier. This book is like having a teacher at home. The result is that the student learns their scales much more quickly, efficiently and correctly from the first playing. The book has 98 full colour pages on quality paper and because it is spiral bound, it sits flat.
