I'll be the first to admit that I get my modes mixed up sometimes. I understand the gist of them just from reading, but I will say I don't really completely understand the application. I normally just play in the notes of the chord in the prog I'm in. Would that not be considered modal, even if limited? Say we are in Fmaj like above. When we are on the IV7(the lydian chord) I'm playing the notes in Bbmaj7 and that would be the Lyian mode, correct? and when we are on the V7(the moxylydian chord) I'm playing the notes in Cdom7 which would be the Moxylidian mode. If we are on the ii7 (dorian chord) I'm playing the notes in Gmin7 which would be in the Dorian mode. Is this correct or am I confused? But I can extend and play more notes than just what makes up the chord correct? But I would still be in Fmaj? I'm asking, I don't know.
