Melodic minor scales - flat key fingering groups

The table is FOR (TEACHERS') REFERENCE ONLY!

Pupils learn the scales one at a time, and the fingering will appear quite logical once it is explained.

The scale fingering groups used in the flat key melodic minor scales are summarized in the table below.
