The impact of music on the brain has been a hot topic in science in the past decade. Now Northwestern researchers for the first time have directly examined what happens after children stop playing a musical instrument after only a few years — a common childhood experience.

Compared to peers with no musical training, adults with one to five years of musical training as children had enhanced brain responses to complex sounds, making them more effective at pulling out the fundamental frequency of the sound signal.

The fundamental frequency, which is the lowest frequency in sound, is crucial for speech and music perception, allowing recognition of sounds in complex and noisy auditory environments.
