Abstract<\/h5>\n\n\n\n

Background: Music is increasingly recognised as a non-pharmacological modulator of cardiovascular autonomic function [1]. However, it remains unclear which musical features drive these effects, whether music alters mean autonomic tone or variability, and whether changes persist beyond listening.<\/p>\n\n\n\n

Purpose: To quantify feature-specific autonomic responses to music and characterise acute and post-listening modulation of heart rate variability (HRV), a clinically relevant marker of vagal function and cardiovascular risk.<\/p>\n\n\n\n

Methods: RR data were analysed from the HeartFM study [2], in which 126 participants (74 women; mean 43.3 years [95%CI 40.5\u201346.0]) listened to 9 piano tracks selected from a pool of 30 (Fig.2A). Of these, 34 had complete baseline and post-listening (endline) recordings. Time-domain (RMSSD, SDNN) and frequency-domain HRV metrics (LF and HF power, two spectral methods) were computed in 60s windows. Track-level analyses examined within-track HRV mean (HRV_mean) and standard deviation (HRV_std). Musical predictors included tempo and loudness, within-track acoustic spread, and phrase-arc structure (mean length and variability). Significance was assessed using ANOVA\/Kruskal\u2013Wallis, correlation analyses with FDR correction, and effect size with Cohen\u2019s d.<\/p>\n\n\n\n

Results: No musical feature influenced HRV_mean at the track level. HRV_std, however, was strongly modulated by music. Tempo showed a stepwise suppression of HRV_std across all indices (\u03b7\u00b2=0.052\u20130.069; q<10\u207b\u00b9\u2079), with faster tracks producing progressively lower within-track variability (RMSSD_std track-level r=\u22120.81; 111\/126 participants negative, p<10\u207b\u00b9\u2079). Within-track tempo std predicted lower HRV_std (\u03c1=\u22120.24; 109\/126 negative), suggesting suppressive mechanism of wider tempo deviations. Loudness showed a weaker effect driven exclusively by the loudest tracks (\u03b7\u00b2\u22480.01\u20130.02), with medium and soft levels statistically indistinguishable. Greater loudness phrase arc length and variability suppressed HRV_std. See Fig.1.<\/p>\n\n\n\n

At session level, HRV_mean did not shift during music, but autonomic fluctuation increased (SDNN_std d=0.93; LF_std d=0.56; RMSSD_std d=0.46), reflecting dynamic engagement rather than a steady-state shift. Endline HRV_mean exceeded baseline (RMSSD +22%, SDNN +20%, both q<0.05) with no regression-to-mean effect, consistent with parasympathetic upregulation. Spectral HRV_mean power changes were not significant after FDR correction. HRV_std elevation persists at endline (SDNN_std p<0.021) while spectral variability normalised. See Fig.2.<\/p>\n\n\n\n

Conclusions: Music modulates autonomic dynamics by altering variability during listening and enhancing vagal tone after exposure. These findings suggest music may “exercise” autonomic flexibility, potentially through entrainment [3], rather than simply induce relaxation. This has implications for the implementation of music-based interventions targeting autonomic flexibility in cardiovascular prevention and recovery.<\/p>\n\n\n\n
