In my submission "A Brief History of Modulation in Musical Rhetoric and Brahms' Harmonic Ambiguity ", I identify the need for a study to correlate musical devices and mental states. The first step is to develop[ a catalog of such devices. These include among many effects, modulation (shifts in tonicity), silence, unison, changes in rhythmic texture etc.
By using the term "mental states", I choose a broader field than mere "emotion".
With an understanding of composition/improvisation (generative), there are a great many possibilities. Just within modulation, Max Reger has developed an extensive catalog of the devices, alas no mention is made of effect on an audience. Rameau in his treatise on Harmony discusses very briefly an emotional response to chromatic modulation (please see my article for the citation specifics; Reger is not cited in this paper yet. It remains in an unfinished form: more than a few citations TBD.
Gee, how do I put a citation here? - simple footnote:
