>>11395689yeah but obviously there are chords which are several notes played together and there are scales/modes, which can be played as arpeggios, which is basically a chord. the scales have different feelings to them, but i think what's more effective in bringing out an emotional reaction to music is larger changes temporally.
by the way, hans zimmer talks a little about how there is a kind of meaning/emotion embedded in note sequences. in one of his songs there's a series of 3 notes that each convey a message.
