Ebook Double Scales, Systematically Fingered

The fingering of a right-hand scale having a given number of sharps corresponds to that of a left-hand scale having the same number of flats, and vice versa.

For example: If the following two scales are played together, the black and White keys will be found to follow each other in the same order, and the same fingering Will be used in both hands.
