Hi guys I've been hearing from friends, beginners etc that they are facing a great difficulty in memorizing the interval structure of the modes. Recently I've come across a relatively easy and systematic method of memorizing the Modes from one of my friends. So thought about sharing with you fellas out there.
This is my first post so I am trying my best to keep it simple and short. Firstly I am listing the modes in order of appearance, with the interval structure of each of them:
1. Ionian - 1 2 3 4 5 6 7 8
2. Dorian - 1 2 b3 4 5 6 b7 8
3. Phrygian - 1 b2 b3 4 5 b6 b7 8
4. Lydian - 1 2 3 #4 5 6 7 8
5. Mixolydian - 1 2 3 4 5 6 b7 8
6. Aeolian - 1 2 b3 4 5 b6 b7 8
7. Locrian - 1 b2 b3 4 b5 b6 b7 8
Now lets arrange the modes so that we can memorize them in a relatively systematic way:
1) Lydian: 1 2 3 #4 5 6 7 8 (ONLY MODE WITH A SHARP NOTE i.e #4)
2) Ionian: 1 2 3 4 5 6 7 8 (NO FLATS AND SHARPS )
3) Mixolydian: 1 2 3 4 5 6 b7 8 ( b7 )
4) Dorian: 1 2 b3 4 5 6 b7 8 ( b3, b7 )
5) Aeolian: 1 2 b3 4 5 b6 b7 8 ( b3, b6, b7 )
6) Phrygian: 1 b2 b3 4 5 b6 b7 8 (b2, b3, b6, b7 )
7) Locrian: 1 b2 b3 4 b5 b6 b7 8 (b2, b3, b5, b6, b7 )
Thus if arranged in this order, each successive mode has only one interval which is different than the mode before it.
NOW the trick:
1) Lydian is the only note with a # note
2) Ionian has no sharp or flat note
3) firstly memorize "L I M D A P L" (The initials of each mode in this sequence)
4) among all the modes (starting from Mixolydian) in 1 and 4 there is no flat notes.
5) now memorize the sequence:
L: #4
I:
M: b7
D: b3, b7
A: b3, b6,b7
P: b2,b3, b6,b7
L: b2,b3, b5,b6,b7
6) This is just a guide which worked for me, hope this will work for you too. Please do forgive for any wrong English or you find any place to be a bit confusing keeping in mind that this is my first post. But please do comment if you find any. It'll help me to improve my future posts.
