Interval names

[dwest2419]

I been studying about musical intervals am I correct on this....

Ionian:
1= Root
2nd = Major second
3rd = Major third
4th = Perfect fourth
5th = Perfect fifth
6th = Major sixth
7th = Major seventh
8th = Octave

Dorian
1 = Root
2nd = Major second
b3 = Minor third
4th = Perfect fourth
5th = Perfect fifth
6th = Major sixth
b7 = Minor seventh
8th = Octave

Phrygian
1 = Root
b2 = Minor second
b3 = Minor third
4th = Perfect fourth
5th = Perfect fifth
b6 = Minor sixth
b7th = Minor seventh
8th = Octave

Lydian
1 = Root
2nd = Major Second
3rd = Major third
#4 = Sharp fourth
5th = Perfect fifth
6th = Major sixth
7th = Major Seventh
8th = Octave

Mixolydian
1 = Root
2nd = Major Second
3rd = Major third
4th = Perfect fourth
5th = Perfect fifth
6th = Major sixth
b7 = Minor seventh
8th = Octave

Locrian
1 = Root
b2 = Minor Second
b3 = Minor third
4th = perfect fourth
b5 = Diminished fifth
b6 = Minor sixth
b7 = Minor seventh
8th = Octave

I was just surprised to see locrian had a perfect fourth!?

I see one mistake: Phrygian should have a b7.

I never did learn how to put your method into use, here is what I use. Offered for what it is worth.

Major Scale Box Pattern

E|---7---|--R(8)-|-------|---2---| 1st string
B|-------|---5---|-------|---6---|
G|---2---|-------|---3---|---4---| 
D|---6---|-------|---7---|--R(8)-|
A|---3---|---4---|-------|---5---|
E|-------|---R---|-------|---2---| 6th string 
Place the root and the other intervals (scale degrees) are always
in the same spot waiting on you.  

Want the 3rd interval it's always up a string and back one
fret - from the root.  Want the 5th its up a string and over two frets, or 
just below the R.  The 6th is over the 3.  The 8 is over the 5, etc.

Scales
• Major Scale = R-2-3-4-5-6-7 Home base
• Major Pentatonic = R-2-3-5-6 Leave out the 4 & 7
• Natural Minor Scale = R-2-b3-4-5-b6-b7 Major scale with the 3, 6 & 7 flatted.
• Minor Pentatonic = R-b3-4-5-b7 Leave out the 2 & 6.
• Blues = R-b3-4-b5-5-b7 Minor pentatonic with the blue note b5 added.
• Harmonic Minor Scale = R-2-b3-4-5-b6-7 Natural minor with a natural 7.
• Melodic Minor Scale = R-2-b3-4-5-6-7 Major scale with a b3.
Let the major scale be your home base then change a few notes and you have something different. No need to memorize a zillion patterns. Let the major scale pattern be your go to pattern - then adapt/adjust from there.

Major modes
• Ionian same as the Major Scale.
• Lydian use the major scale and sharp the 4 - yes, it’s that simple.
• Mixolydian use the major scale and flat the 7. Change one note.....
Minor Modes
• Aeolian same as the Natural Minor scale.
• Dorian use the Natural Minor scale and sharp the b6 back to a natural 6. Change one note.
• Phrygian use the Natural Minor scale and flat the 2. Again change one note.
• Locrian use the Natural Minor scale and flat the 2 and the 5. OK here you have to change two notes.

This I can use. I was not able to connect the dots with naming them major or minor, perfect, etc. Now that I have spent some time with your method. I see that it's just names.

If R-2-b3-4-5-6-b7 helps - help yourself to scale degrees.

Good luck which ever way you elect to go.

Aeolian
1 = Root
2nd = Major second
b3rd = Minor third
4th = Perfect fourth
5th = Perfect fifth
b6 = Minor sixth
b7 = Minor seventh
8th = Octave

If forgot about Aeolian
