Too under stand modes is to a painter under standing color.
Cmaj mode has no sharps or flats..... CDEFGABC
Cmaj Ionian mode Major chord prog... pop mainly ( happy sound)
Dmin Dorian mode Minor chord prog.... Blues early metal (ratt,dokken, scorpians)
Emin Phrygian mode Minor chord prog... spanish flavor (Ingwie kills on this)
Fmaj Lydian mode major really jazzy outside stuff
Gmaj Mixalydian major mode Clapton, Satch, country good stuff
A minor the Natural minor most use rock metal mode, next to penetonic
B Locrian dark minor flated 2nd and flated 5th the darkest evil mode known to manthis mode is newer metals darkest all.
Now all these modes are the same scale. (NO SHARPS OR FLATS) Just different root notes. But the color that you paint with Happy or dark.... paints the color you want.
Think if Piccaso only had 3 colors
Now do not forget Maj & Minor Penetoinics, Blues scales(there are 6), dimished, Harmonic minor, augmented, melodic minor, chromatic minor penetonic with chromatic connecting notes, chromatic and all the variations off the Major modes to include Gypsie, Egyption and Hungarian minors. Plus 1000s more. They are all colors
Choose your color the canvas is yours....Never say I never shared nothing, this lesson if comprehended will open your whole music universe!
Peace choose your colors to reflect how you feel!!!
