music

An earworm — scientifically termed involuntary musical imagery (INMI) — is a short, catchy melodic fragment that loops involuntarily in consciousness without deliberate effort or intention. They arise from how auditory memory and the brain's phonological loop rehearse simple, repetitive hooks, and are triggered by recent exposure, stress, and idle mind-wandering. Research shows certain musical features — simple rhythmic patterns, unexpected melodic intervals, and familiarity — make songs more prone to earworm status. Understanding the cognitive machinery behind them reveals how memory, attention, and prediction interact in the brain.

How music affects the brain: dopamine release and chills, why songs get stuck as earworms, how music activates autobiographical memory, and the universality of rhythm across cultures.

Why music affects emotions explained: dopamine and chills, prediction and expectation, why sad music feels good, earworms, and what neuroscience reveals about music's grip on the brain.
