What is an earworm?

An earworm is the spontaneous mental recall and repetition of a piece of music, often referred to in everyday terms as having a song stuck in one’s head. This is a common and widespread experience, reported by over 90% of people in large-scale surveys. Earworms are also called involuntary musical imagery (INMI). Ongoing research in Durham focuses on:

  • the causes & possible functions of earworms
  • using musical features to predict when & why tunes become earworms

Our research has been featured in a wide variety of news outlets, including The New York Times, The Wall Street Journal, CNN, The Guardian, and The Conversation.

Summary: This work reveals that the likelihood that a tune becomes an earworm can be predicted by both extra-musical features (measures of song popularity and recency), as well as musical features, including the tune’s tempo and melodic contour patterns. The following playlist includes the top 9 earworm tunes named by 3,000 participants in the study:

Summary: This work introduces a new method for measuring the tempo of earworm episodes as they occur during daily life. Results reveal that earworms for canonical tunes are recalled very close to the original, recorded tempo and earworm tempo is systematically related to features of concurrent mood (arousal/alertness).

Jakubowski, K. (2015). Investigating Temporal and Melodic Aspects of Musical Imagery. (PhD thesis, Goldsmiths, University of London).

Summary: The results of five experiments investigating temporal and melodic aspects of voluntary and involuntary musical imagery are reported. Together, these studies reveal new insights on the features, phenomenology, and possible functions of imagined music.

Summary: This study is the first to reveal that aspects of brain structure correlate with earworm frequency and emotional appraisal of the earworm experience.

Summary: This study represents a novel, ‘big data’ approach to studying earworms by collating and classifying naturalistic, unprompted reports of earworm experiences on Twitter.

Summary: This study is the first large-scale investigation into the diversity and commonalities between strategies used to dispel unwanted earworms.
