The excercise asks me to build a progression from a mode, it says "think of other chords in your mode".
I did the G as you mention - how do I get another one from that mode?
I assumed I would just pick other notes from that scale and then build a triad in the same way (i.e.with a new starting point) staying within the scale but I've obviously go the wrong end of the stick.
Really appreciate the help
