here are all the Diatonic Modes...Ill do them out of the Key of C so as not to use flats or sharps
I - Ionian - Considered
THE Major scale. The third note is an E in a Major 3rd position in relation to the root C so it is implying that it is a Major scale. The 7th is also Major...It goes:
C - D - E - F - G - A - B - C
ii Dorian --utilizes the same notes as in C Ionian but starts on the the second note ( "D")......Its 3rd note falls into a minor position relative to the root D, so it is implied as a Minor based scale
D - E - F - G - A - B - C - D
iii Phrygian - starts on an E in the key of C...its third note, the G, is in a minor position in relation to the root E
E - F - G - A - B - C - D - E
IV Lydian...starts on the F out of Key of C. The third note, A, is in a major position relative to the F, so it is Major
F - G - A - B - C - D - E - F
V Mixolydian...starts on the G out of Key of C. The third note, B, is in a major position relative to the G, so it is Major
G - A - B - C - D - E - F - G
vi Aeolian -- Considered
the MINOR scale. The third note, C, is in a minor position to the A root in the Key of C
A - B - C - D - E - F - G - A
vii Locrian -- Is a minor scale ( the third note "D" in a minor position relative to the root B) but it is also considered half-diminished because the 5th note, F, is in a fklatted 5th position in relation to the key "B")
B - C - D - E - F - G - A - B
So, for Diatonic Modes: Ionian, Lydian, and Mixolydian are Major Modes
There are many substitution modes not considered diatonic that are major but im sick of typing
