Skaha - I was listening to some ambient tunes late last night in the dark and was reminded how a couple notes can carry a certain very general emotion. For instance, in the key of Gminor, going from C to D (four to five) sounds like "triumph" to me. Same with seven to eight. Whereas, for instance, going from one to two or six to seven sounds like "suspension" or "expectancy." I've experienced this many times with many different two- or maybe three-note variations in different keys. Anyway, last night I had a crazy, unrealistic, but still exciting idea to put together a sort of dictionary of musical emotions, listing all the keys and all their possible two-note changes and their respective emotions. Then I realized how colossal a task this would be. But even as a fantasy it was exciting. I don't know if that's kinda what you're getting at, but hell, thought I'd put it out there since it was fresh in my head.
