CORE DEFINITION

A piece of music or melody that involuntarily repeats in the mind (Involuntary Musical Imagery). This often occurs because the melody is simple, repetitive, and has unresolved tension (Zeigarnik effect).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Viral dissemination. If you want a slogan or viewpoint to be remembered, design it as an "earworm" structure: simple, rhyming, repetitive, and ideally leave a sense of "incompleteness" that makes the brain unable to resist revisiting it.

anchor

Anchor fast decisions

Short, repetitive melodies with unresolved tension spontaneously loop in the auditory cortex (Involuntary Musical Imagery). The brain has a compulsion to rehearse "incomplete" phrases (similar to the Zeigarnik effect), and the more you try to get rid of it, the more it is reinforced.

MINIMUM ACTION

In progress 0/3

Practice this model in one real situation:

To make people remember information, design it as an "earworm": simple, rhyming, repetitive, and leave a sense of incompleteness
control the length and hook
repeatedly expose it in high-frequency contexts. To get rid of an earworm, use another melody to cover it or engage in a task that requires focused attention to interrupt the loop.
