“Expectancy violations (e.g., harmonic, rhythmic, and/or melodic violations) are strongly correlated to the onset of musical frisson, such that some level of violated expectation may be a prerequisite.” Interesting. The Spotify playlist didn't do much for me, but when I think of a couple moments in songs that always give me chills, they all feature that pattern: Nightwish, Ghost Love Score , Wacken 2013 @ 9:22, affec…

Pure "expectancy violation" again.
Howells is full of these moments. The big, crunchy, discordant Amen in the Gloria of the Magdalen Service is my favourite - where the harmonies are offset by a crescendo/diminuendo/crescendo sequence in the choir, all on the same note.
