I came across some research from several years ago coming out of Northwestern on how music training boosts learning.
“Neuroscience research has shown that music training leads to changes throughout the auditory system that prime musicians for listening challenges beyond music processing. This effect of music training suggests that, akin to physical exercise and its impact on body fitness, music is a resource that tones the brain for auditory fitness.”
Here’s the full citation to the published paper:
