Ooo, I think it's starting to fall into place.
If I try to combine what you're saying with what "oldhippiegal" is talking about regarding note number within a scale, I come up with this table in relation to the C major scale, is it correct? Especially the Note column?
Degree_____Interval_________Semitones______Note Name___Note Number
1________Root/unison_________0_____________C____________1
_________Minor 2nd___________1
2________Major 2nd___________2_____________D____________2
_________Minor Third__________3
3________Major Third__________4_____________E____________3
4________Perfect Fourth_______5______________F __________4
_________Tritone_____________6
5________Perfect Fifth_________7______________G__________5
_________Minor 6th____________8
6________Major 6th____________9_____________A___________6
_________Minor 7th___________10
7________Major 7th___________11_____________B___________7
8________Octave_____________12_____________C______ _____8
_________Oct. Maj 2nd_________14_____________D__________10
Is the degree the same as the note number of the scale, or just in the C major scale?
