It was investigated to what extent musical expertise influences the auditory processing of harmonicity by recording event‐related potentials. Thirty‐four participants (18 musicians and 16 controls) were asked to listen to hundreds of chords, differing in their degree of consonance, their complexity (from two to six composing sounds) and their range (distance of two adjacent pitches, from quartertones to more than 18 semitone steps). The task consisted of detecting rare targets. An early… 
Neural correlates of acoustic dissonance in music: The role of musicianship, schematic and veridical expectations
This study suggests that, at early time windows, dissonance is processed based on acoustic deviance independently of syntactic rules, however, at longer latencies, listeners may be able to engage integration mechanisms and further processes of attentional and structural analysis dependent on musical hierarchies, which are enhanced in musicians.
Early neural responses underlie advantages for consonance over dissonance
Early processing of consonance and dissonance in human auditory cortex
Results indicate that the neural mechanisms responsible for pitch processing exhibit an intrinsic differential response to concurrent consonant and dissonant pitch combinations, suggesting that the perception of consonance and dissonance might be an emergent property of the pitch processing system in human auditory cortex.
Cross-domain effect of pitch processing in lexical and melodic contexts reflected by non-musicians: An MEG study
The brain-behavior results showed a positive correlation between the performance of musical pitch tasks and the activation of the left frontotemporal cortical regions elicited by lexical tones, suggesting that the cross-domain effect of language and music could be generalized to people without formal music training.
Shared neural mechanisms for processing emotions in music and vocalizations
The neural mechanisms involved in the processing of emotional vocalizations and music seemed to involve common neural mechanisms, and how emotionally negative stimuli tended to be in Minor key, and positive stimuli in Major key, shedding some lights on the brain ability to understand music.
Dissonant endings of chord progressions elicit a larger ERAN than ambiguous endings in musicians.
An early sensitivity of musicians to dissonance, which is processed as less expected than tonal irregularities, is suggested, even though violations of harmonic expectancies are detected by all listeners, musical training modulates how different violations of the musical context are processed.
Transient and sustained processing of musical consonance in auditory cortex and the effect of musicality.
The MEG study shows how energy-balanced sounds can focus the response waves on the consonance-dissonance distinction rather than energy changes, and how source modeling techniques can be used to measure the sustained fields associated with extended consonant and dissonant sounds.
Modeling and MEG evidence of early consonance processing in auditory cortex
A striking match is found between the predicted and the observed latency of the POR as elicited by the dyads, suggesting that consonance processing starts early in human auditory cortex and may share the network mechanisms that are responsible for (single) pitch processing.


Importance of the left auditory areas in chord discrimination in music experts as demonstrated by MEG
The brain basis behind musical competence in its various forms is not yet known. To determine the pattern of hemispheric lateralization during sound‐change discrimination, we recorded the magnetic
Consonance and dissonance of musical chords: neural correlates in auditory cortex of monkeys and humans.
The relevance of synchronous phase-locked neural ensemble activity in A1 for the physiological representation of sensory dissonance in humans is supported and the merits of complementary monkey/human studies in the investigation of neural substrates underlying auditory perception are highlighted.
Neural Correlates of Consonance, Dissonance, and the Hierarchy of Musical Pitch in the Human Brainstem
The results suggest that brainstem neural mechanisms mediating pitch processing show preferential encoding of consonant musical relationships and, furthermore, preserve the hierarchical pitch relationships found in music, even for individuals without formal musical training.
THE AIM OF THIS SERIES OF experiments was to determine whether consonant and dissonant chords elicit similar or different electrophysiological effects out of a musical context and whether these
A Comparison of Contour and Interval Processing in Musicians and Nonmusicians Using Event‐Related Potentials
Findings suggest that (a) contour processing is more basic, (b) interval processing may be more affected than contour by experience, and (c) similar brain networks are involved in generating the P3a and P3b in musicians and nonmusicians.

To examine whether consonance has some role in audition of nonhumans, three Japanese monkeys were trained to discriminate simultaneous two-tone complexes (chords) to suggest that the consonance of chords affected the performances of monkeys.
Increased auditory cortical representation in musicians
The results, when interpreted with evidence for modified somatosensory representations of the fingering digits in skilled violinists, suggest that use-dependent functional reorganization extends across the sensory cortices to reflect the pattern of sensory input processed by the subject during development of musical skill.
The basis of musical consonance as revealed by congenital amusia
The results of this testing of sound preferences in individuals with congenital amusia suggest the need to integrate harmonicity as a foundation of music preferences, and illustrate how amusics may be used to investigate normal auditory function.
The “consonance effect” and the hemispheres: A study on a split-brain patient
The results suggest that the right-hemispheric superiority in appreciating consonance might hide the inability of the right hemisphere to classify dissonant chords as unpleasant in the split-brain, whereas the left hemisphere seems capable to differently label the pleasantness of consonant and dissonant chord, even if it is more sensitive to dissonance.
