Single chords convey distinct emotional qualities to both naïve and expert listeners.
Previous research on music and emotions has been able to pinpoint many structural features conveying emotions. Empirical research on vertical harmony’s emotional qualities, however, has been rare. The main studies in harmony and emotions usually concern the horizontal aspects of harmony, ignoring emotional qualities of chords as such.
An empirical experiment was conducted where participants (N = 269) evaluated pre-chosen chords on a 9-item scale of given emotional dimensions. 14 different chords (major, minor, diminished, augmented triads and dominant, major and minor seventh chords with inversions) were played with two distinct timbres (piano and strings).
The results suggest significant differences in emotion perception across chords. These were consistent with notions about musical conventions, while providing novel data on how seventh chords affect emotion perception. The inversions and timbre also contributed to the evaluations. Moreover, certain chords played on the strings scored moderately high on the dimension of ‘nostalgia/longing,’ which is usually held as a musical emotion rising only from extra-musical connotations and conditioning, not intrinsically from the structural features of the music. The role of background variables to the results was largely negligible, suggesting the capacity of vertical harmony to convey distinct emotional qualities to both naïve and expert listeners

Harmonic organisation conveys both universal and culture-specific cues for emotional expression in music
Previous research conducted on the cross-cultural perception of music and its emotional content has established that emotions can be communicated across cultures at least on a rudimentary level. Here, we report a cross-cultural study with participants originating from two tribes in northwest Pakistan (Khow and Kalash) and the United Kingdom, with both groups being naïve to the music of the other respective culture. We explored how participants assessed emotional connotations of various Western and non-Western harmonisation styles, and whether cultural familiarity with a harmonic idiom such as major and minor mode would consistently relate to emotion communication. The results indicate that Western concepts of harmony are not relevant for participants unexposed to Western music when other emotional cues (tempo, pitch height, articulation, timbre) are kept relatively constant. At the same time, harmonic style alone has the ability to colour the emotional expression in music if it taps the appropriate cultural connotations. The preference for one harmonisation style over another, including the major-happy/minor-sad distinction, is influenced by culture. Finally, our findings suggest that although differences emerge across different harmonisation styles, acoustic roughness influences the expression of emotion in similar ways across cultures; preference for consonance however seems to be dependent on cultural familiarity
Neural and physiological data from participants listening to affective music
Music provides a means of communicating affective meaning. However, the neurological mechanisms by which music induces affect are not fully understood. Our project sought to investigate this through a series of experiments into how humans react to affective musical stimuli and how physiological and neurological signals recorded from those participants change in accordance with self-reported changes in affect. In this paper, the datasets recorded over the course of this project are presented, including details of the musical stimuli, participant reports of their felt changes in affective states as they listened to the music, and concomitant recordings of physiological and neurological activity. We also include non-identifying meta data on our participant populations for purposes of further exploratory analysis. This data provides a large and valuable novel resource for researchers investigating emotion, music, and how they affect our neural and physiological activity

Charm multiplicity and the branching ratios of inclusive charmless b quark decays in the general two-Higgs-doublet models
In the framework of general two-Higgs-doublet models, we calculate the
branching ratios of various inclusive charmless b decays by using the low
energy effective Hamiltonian including next-to-leading order QCD corrections,
and examine the current status and the new physics effects on the determination
of the charm multiplicity and semileptonic branching ratio .
Within the considered parameter space, the enhancement to the ratio due to the charged-Higgs penguins can be as large as a factor of 8 (3) in
the model III (II), while the ratio can be increased from
the standard model prediction of 2.49% to 4.91% (2.99%) in the model III (II).
Consequently, the value of and can be decreased simultaneously
in the model III. The central value of will be lowered slightly by
about 0.003, but the ratio can be reduced significantly from the
theoretical prediction of in the SM to , for GeV, respectively. We find that
the predicted and the measured now agree within roughly one
standard deviation after taking into account the effects of gluonic charged
Higgs penguins in the model III with a relatively light charged Higgs boson.Comment: 25 pages, Latex file, axodraw.sty, 6 figures. Final version to be
