In minor the sixth and seventh degrees of the scale are raised both
ascending and descending, when used in harmonies containing the
leading-tone as a chord-tone. They are unaltered both ascending and
descending in harmonies containing the sixth degree of the scale as a
chord-tone. In other harmonies they are raised in ascending only.

The sixth or seventh degrees may be chromatically altered with only one
note intervening. [Fig. 51.]
