What's the big deal about them ? .
while improvising i'm thinking (a monologue following) A Chord .. hmmm.. maybe a little sweep , some 5/7 - 5 to 8 moves... hmmm .... A Chord ... (is this in A-major scale?, it could be in D Major too... I'll wait for the next chord to check....) ... ok it's in A-major scale... so I picture : A B #C D E #F #G A ... play any of those notes .. but not 2nds r 7ths!!! it'll sound crappy... hmmm .. some licks, some s/7...
All right I know that's not really what you must be thinking, it's different for me too.. but sometimes I'm like that... picturing what to do... and when i'm like that... should I be thinking "modes"?
What modes are for me is this:
(let's remember them: Jonic - Dorian - Phrygian - Lydian - Mixolydian - Aeolian - Locrian)
I have (for example) a C-Major Scale :
C D E F G A B C
e ------0-1-3-5-7-8--
B --1-3----------------
If i would want to just start that run not 2ndString-1stFret (C), but to start it in D, I would play:
D E F G A B C D
e ------0-1-3-5-7-8-10-
B ----3----------------
And that's D Dorian!! (2nd Note, 2nd mode)
A-Major (Jonian) Scale:
A B #C D E #F #G A
e --------0-2-4-5-----
B ----0-2--------------
G --2
And if I would want to play it starting from #C :
e -----0-2-4-5-7-9---
B ----2--------------
G -
And that's #C Phrygian (3rd Note from A Scale... 3rd mode for #C)! so easy!
My question is:
Are modes just intended to classify scales??
are they just for saying "Oh, yeah that's just a run in A-Phrygian mode" or.. "Oh, that songs starts with DMaj Chord, but uses CMaj and FMaj chords... it must be in D Dorian mode i'm so cool I sound smart"
When a song starts for example in F major .. I think... allright, in F-major scale. but then the Bdim sounds instead of the BdMaj... I won't start saying oh I think it's F Lydian .. I'll just say.. It's in C Major!! .. right???
Other example:
-1------------5-7-8- <-- is that in D Dorian????
-3-----5-6-8------- it's in C Maj... come on!
-2-/-7----------------
-0---------------------
so... concluding... knowing modes CAN improve your playing? isn't just the same that knowing all of the Major and Minor scales?
If i'm jamming with another guitarrist and he says now change to D dorian! should I think "Oh.. C major scale... all right let's jam!" or knowing the modes will make a difference and I should consider them?
