I came across this sentence, reading A Theory of Harmony, John Stainer, P 9 item 27:
The scale of a relative minor consists of the same notes as that of its relative major, with one exception, namely, the seventh degree (the fifth of its relative major) which is raised one semitone.
This seems to imply that a major scale's relative minor doesn't share its notes.
- A minor is the relative minor of C major.
- The fifth degree of C major is G.
- By 1. and 2., with the statement above the seventh degree of A minor is G#.
It seems I'm misunderstanding the above quote/musical terms. Can someone here clarify its meaning for me? Or was this statement just a bloop?
