The Vowel as an Acoustic, Emotional, and Biological Stimulus in Music Pedagogy

This research explores the multidimensional role of vowels as acoustic, emotional, and biological stimuli within the context of music pedagogy. The study argues that vowels are not neutral phonological units but active triggers of affective and physiological processes. Using the formant architecture of the standard Serbian language as a baseline, the analysis demonstrates how specific vowel configurations are instinctively associated with spatial and emotional archetypes. Through the lens of the facial feedback hypothesis, the research shows that the mechanical activation of orofacial muscles during vowel production functions as a somatic stimulus, modulating the performer’s internal affective state. Neurophysiological evidence further confirms that vowels elicit stable cortical responses, while empirical studies highlight their capacity to regulate biomarkers of stress, immunity, and social bonding through collective singing. By integrating insights from acoustic phonetics, biomechanics, and psychophysiology, this work repositions the vowel as a fundamental pedagogical tool – one that simultaneously shapes technical vocalization, authentic emotional expression, and biological regulation. The findings advocate for a holistic approach to music education, particularly for children and adolescents, where vowel articulation fosters systemic balance, resilience, and artistic integrity.
