Subject: [AUDITORY] Emotional Impact of Scale Degrees in Relation to Chord Root Perception From: Dennis Hamm <dennis@xxxxxxxx> Date: Fri, 11 Apr 2025 16:19:27 -0700Dear colleagues, As a professional jazz pianist exploring the emotional impact of harmony, I=E2= =80=99ve recently delved into how individual scale degrees within chords con= tribute to emotional expression. One key observation is that each added scal= e degree imparts a distinct emotional color=E2=80=94but intriguingly, its af= fective quality can shift dramatically depending on whether the underlying c= hord is Major or Minor. For example, adding an F=E2=99=AF to a C Major triad might evoke feelings of= enchantment or wonder. However, adding the same pitch to a C Minor triad of= ten generates a much darker, even malevolent emotional response. In collaboration with Tuomas Eerola and Imre Lahdelma at Durham University (= whose work with Pakistani tribal participants revealed that Major chords can= be perceived as odd or unsettling, and Minor chords as positive!), I=E2=80=99= ve created a brief survey to test this theory. If you=E2=80=99re interested in contributing to this research=E2=80=94or sim= ply curious about how you personally respond to harmonic variation=E2=80=94y= ou can participate here: https://sentisonics.com/hes/ Please feel free to share this with students and non-musicians as well. Than= k you! Best regards, Dennis Hamm dennis@xxxxxxxx=
