Sx/Sp or Sp/Sx can change the emotional qualities of a person. Like loneliness, feelings of being outcast, left to ones own devices, socially misunderstood, marooned, rebelling against the majority etc. grants different visual or acoustic chromatics if represented through various media. Colors become washed out, suddenly there is beauty in decay and disillusionment/distrust for the artifice of perfect beauty (rust, decay, abandonment in the foreground; the natural quality of things is not "sanitized" "unblemished" "pure"). Solitary towers may parallel the intimate focus of one individual's inner life as symbols from romanticist, Gothic obsession with the individual, Byronic hero. Melodies turn more sinister in tone, more flat/sharp notes, minors utilized (Enharmonic modulation?) compositions may evoke feelings of strange, cold, alien, "paranormal," oneiric, trippy (dirty) ascendence, etc. Emphasis is not on conveying a narrative through musical composition, a "story," instead capturing an ambience of feelings, a comforting solitude of texture of notes that wrap around the 'soul' of the listener, conserving, shielding away from the cacophony of the world.
None of this, however ties to any genre in general. On one of my course we learned that film noir was never listed as a filmic genre. Still, after its hayday, "noir" continued to pop up in various types of films, detuning their style by adding more grittiness, edge, social criticism, colder/darker tone, an eerie psychological depth, mystery, a blurring of the good / bad, thus steering away from straight happy ends toward more complexity, seriousness.
And even if these are true, it doesn't change the very fact, that all can be imitated, coppycatted, captured and re-represented (by so/sxs, so/sp, sx/sos) under the (sun)light of the public eye. The way Batman or a subversive idea can contained and become public property (counterculture becomes culture). So the most important factor that one has to discern to be able to differentiate (needs careful dissection) is the following: "raw communication" 1-on-1 without masspersonal intent. Or in other words: no games, no bluffing, no sarcasm, duplicity but direct intimacy. It strips naked to talk to you. Would you bare your soul for him/her?
