Could I just confirm my understanding of the Course Offsets part of the Courses article.
If I'm using the major scale: CDEFGAB
Then the first course would be CDEFGAB, obviously.
If I set the second course to have an offset of one scale step, then the second course would be DEFGABC. That's perfectly clear - we just move up the scale.
If I set the second course to have an offset of one semitone, would it then be: C# D# F F# G# A# C ?
