This study explores how personality traits and circadian preferences (chronotypes) influence music preferences and engagement. Two hundred forty participants completed the morningness–eveningness questionnaire, a musical preferences list with 23 genres, and a music engagement scale. Results from the correlation analysis reveal distinct relationships between personality, time-of-day preferences, and music use. Openness to experience strongly predicted music engagement for identity expression, social connection, and emotional regulation, while neuroticism is linked to using music for emotional coping. Extraversion is correlated with social and physical engagement with music, whereas conscientious individuals engage less with music for emotional processing. Circadian preferences also shape music choices and listening habits. Morning types (M-Types) favor structured and soothing music, such as devotional and slokas/chants, while evening types (E-Types) preferred high-energy and complex genres like rock and western classical. Listening times align with chronotypes, as E-Type predominantly listen to music at night, whereas M-Type prefer morning and evening. These findings provide insights into how biological rhythms and personality shape music engagement and preference.
