Study Notes

Music and brain function

  • Playing a musical instrument can change the brain’s anatomy, function, and how it works.
  • Research shows that learning to play a musical instrument has a lasting effect on how the nervous system responds to sound.
  • The study involved 45 volunteers: half had taken music classes and played an instrument, while the other half had not.

Sound and electrical activity

  • Electrodes are placed on volunteers' heads to capture electrical activity in the brain in response to sound.
  • This electrical activity is analyzed to determine how the nervous system responds to speech, music, and other sounds.

Musicians vs. Non-musicians

  • The study found that musicians had larger neural responses to sound compared to non-musicians.
  • The computer screen graph, or picture of the sound, was larger for the volunteers who played music.
  • This suggests that musicians are better at processing sounds, particularly the fundamental frequency that carries pitch information.

Impact on hearing

  • The study also found that musicians have better hearing, especially as they age.
  • This is because the nervous system is better at responding to sounds that the brain has learned are important.
  • Musicians are better at identifying and isolating the sounds they are interested in, such as their own instrument.

Music and memory

  • Playing music forces the brain to remember the notes just played, strengthening memory pathways.
  • This could also help with learning other languages or subjects.

The "Mozart Effect"

  • The study emphasizes the importance of actively playing music rather than passively listening, disproving the idea that listening to music alone is enough.

Importance of music education

  • The research suggests that music lessons should be included in education despite economic difficulties.
  • This is because playing music provides a valuable benefit to brain development and hearing health.
