Viccy, if I use the lost chord, will I still have to name it even though I can't find it?
Well it's very irresponsible to lose it in the first place.
I got a little confused with this actually, I was playing The Scale over The Chord, but that makes new chords. I get it now, the chord can be as complex as you want to make it, but then you stick to those notes only (I think).
