TLDR
7-month-old infants were tested with an operant headturn procedure in a similar design and exhibited an identical pattern of responding, and consonance was more important than interval width in determining the perceived similarity of harmonic intervals.
Abstract
Two experiments examined the influence of sensory consonance on the perceptual similarity of simultaneous pairs of complex tones (harmonic intervals). In experiment 1, adults heard a sequence of five consonant intervals (each a perfect fifth, or 7 semitones) and judged whether a subsequently presented test interval was a member of the sequence. Discrimination performance was better when the test interval was dissonant (tritone, 6 semitones) rather than consonant (perfect fourth, 5 semitones), despite the fact that the change in interval width was twice as great for the consonant than for the dissonant comparison. In experiment 2, 7‐month‐old infants were tested with an operant headturn procedure in a similar design and exhibited an identical pattern of responding. Hence, for both age groups, consonance was more important than interval width in determining the perceived similarity of harmonic intervals.

Relations among musical skills, phonological processing, and early reading ability in preschool children.

TL;DR: Music perception appears to tap auditory mechanisms related to reading that only partially overlap with those related to phonological awareness, suggesting that both linguistic and nonlinguistic general auditory mechanisms are involved in reading.

Universal Recognition of Three Basic Emotions in Music

TL;DR: A crosscultural study with participants from a native African population (Mafa) and Western participants, with both groups being naive to the music of the other respective culture, shows that consonance and permanent sensory dissonance universally influence the perceived pleasantness of music.

Functional specializations for music processing in the human newborn brain

TL;DR: Functional MRI is used to measure brain activity in 1- to 3-day-old newborns while they heard excerpts of Western tonal music and altered versions of the same excerpts, demonstrating that the infant brain shows a hemispheric specialization in processing music as early as the first postnatal hours.

The development of evaluative responses to music:: Infants prefer to listen to consonance over dissonance

TL;DR: For instance, this paper found that infants are similar to adults in their evaluative reactions to consonance and dissonance, and that infants preferred to listen to the original version of a Mozart minuet than to a version altered to contain many dissonant intervals.

Preference for Sensory Consonance in 2- and 4-Month-Old Infants

TL;DR: This article found that 2-and 4-month-old infants preferred to listen to consonant versus dissonant two-tone intervals and found it difficult to recover interest after a sequence of dissonant trials.

Tonal consonance and critical bandwidth.

TL;DR: Evaluation of theories on the explanation of tonal consonance as the singular nature of tone intervals with frequency ratios corresponding with small integer numbers supports the hypothesis that the difference between consonant and dissonant intervals is related to beats of adjacent partials.

Periodicity coding in the auditory system.

TL;DR: The present review summarizes the present knowledge about representation and processing of periodic signals, from the cochlea to the cortex in mammals, and in homologous or analogous anatomical structures as far as these exist and have been investigated in other animals.

A comparison of infants' and adults' sensitivity to western musical structure.

TL;DR: For instance, this article found that infants can detect a 4-semitone change in 1 note that remained within the key and implied dominant harmony (diatonic change) or a 1-semeone change that went outside the key (nondiatonic) but had difficulty with the diatonic change.

Natural Musical Intervals: Evidence From Infant Listeners

TL;DR: This article investigated infants' ability to detect subtle changes to patterns of simultaneous and sequential tones and found that infants detected such changes to pairs of pure tones (intervals) only when the tones were related by simple frequency ratios.

Consonance Theory Part I: Consonance of Dyads

TL;DR: This consonance characteristic turned out to show a simple V curve if consonance is plotted against the frequency percent deviation in a logarithmic scale, and it suggests a dynamic and a static factor in consonance perception.
