hi everyone I have just worked out the modal approach to things but I would like to understand where sus chords fit in because they are neither major or minor since the 3rd is replaced by either the p4 or m2. i was wondering where they fit in, inside the major scale chord sequence. and how do you use the sus notes to highlight what mode you are in. this is what i want to understand. where to use sus chords, why use them, and when to use them.
