Yes, you got it. 1 is the tonic (or root, if you're talking about chords), and the 2, 3, 4, 5, 6, and 7 are all major or perfect intervals from the tonic.
2 = major 2nd
3 = major 3rd
4 = perfect 4th
5 = perfect fifth
6 = major sixth
7 = major seventh
Incidentally, 1 2 3 4 5 6 7 is the formula for the major scale. We use this as the basis for comparison for other scales.
As soon as you start adding accidentals, you get different intervals from the root/tonic:
b2 = minor second
#2 = augmented second
b3 = minor third
#4 = augmented fourth
b5 = diminished fifth
#5 = augmented fifth
b6 = minor sixth
#6 = augmented sixth (probably won't see this much; usually written as b7)
bb7 = diminished seventh
b7 = minor seventh
When you add accidentals, our formula changes, and we no longer have a major scale. 1 2 3 4 5 6 b7 is a mixolydian scale, for example.
The bb7 that you were asking about, it's not a typo. It comes from the spelling of the diminished seventh chord.
maj7 = 1 3 5 7 ("major seven")
7 = 1 3 5 b7 ("dominant seven")
m7 = 1 b3 5 b7 ("minor seven")
ø7 = 1 b3 b5 b7 ("half diminished seven", or "minor seven flat-five")
°7 = 1 b3 b5 bb7 ("fully diminished seven", or "diminished seven")
The ultralocrian mode comes from the harmonic minor scale (1 2 b3 4 5 b6 7), starting on the seventh note. If you arrange the harmonic minor scale to begin on the seventh note, you get this: 7 1 2 b3 4 5 b6
If you then make that 7 into a 1, you get this: 1 b2 b3 b4 b5 b6 bb7
OK, let me ask you about this. In the chart it says under "Major scale and it's mode" it says for Ionian that it's R,2,3,4,5,6,7. And then under Melodic Minor it says R,2,b3,4,5,6,7. So that makes sense, because the (ascending) melodic minor scale is basically the same as the A major scale but with a minor 3rd.
And, again, you are correct.But then for the harmonic minor scale it lists it as R,2,3,4,5,6,7. Shouldn't it be R,2,b3,4,5,b6,7?
I haven't tried this particular .DOC, but OpenOffice, NeoOffice, AbiWord and "I'm sure there's more out there, Ask Dr. Google" should be able to open it.Ugh I don't have MS Office...
