ive learned the modes now (ionian-locrian) and now i want to know how to apply them to my playing. when should i use them? do i use them to solo? do they only work over certain chord progressions or keys? any help will be appreciated. thanks.
Dont make so many friggin threads lmao.

put all your questions into one thread labeled "Help gdm09 with his theory questions!"
different modes will give you different sounds..it all pretty much depends on how you wan your solo to sound

for major pitch you could use the plain old ionian
for minor you could use dorian
there are other major and minor modes within the major scale..but they each have unique note(s) that sperate them from the rest
