Well, i've learnt alot about modes, but everyone failed to explain to me when they are used, i know of one use that you can write a composition with them to get a certain type of sound, but let's say i want that sound inbetween a solo written on say C major, when can i use it ?
When the bass plays a F note for example i can play Lydian ? and when it plays D can i play dorian on it ?
Another question, except the half tone intervals which define the modes, what makes them major/minor ? the harmonization they get from the scale ?
