Frequently asked questions
Why does the scale have eight notes?
The pattern lists seven different notes and then returns to the root note one octave higher, which is why eight notes are shown.
What is the difference between major and minor here?
The two types use different step patterns from the same root, so the third, sixth and seventh notes differ between major and natural minor.
