Here’s one big mistake people often make. Yes, they learn an internalize the sound of a certain mode, but they are only able to noodle to a backing track. It’s crucial to also learn the chords of a mode and then try to compose something of your own that you can relate to that you understand and that can use in a composing context. This is where the magic begins - maybe not for aeolian as most guys know aeolian, Ionian and dorian, but the rest has some nice twists - just ask people like Sting...he knows about lydian verses very well..
