i totally get the last bit its what sounds good to you and feels gd over those chords that makes the song work. so just a recap all the modes are the same but when i play the mode inion the shape differs from aelion and they sound different but yet u say they use the same notes? how can this be. because there is minor and major modes. dont they have different notes to each other? from the minor and major. is the difference just purely from starting at a different root note?.
