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.
