Abstract
By measuring the auditory brainstem response to two musical intervals,
the major sixth (E3 and G2) and the minor seventh (E3 and F\#2),
we found that musicians have a more specialized sensory system for
processing behaviorally relevant aspects of sound. Musicians had
heightened responses to the harmonics of the upper tone (E), as well
as certain combination tones (sum tones) generated by nonlinear processing
in the auditory system. In music, the upper note is typically carried
by the upper voice, and the enhancement of the upper tone likely
reflects musicians' extensive experience attending to the upper voice.
Neural phase locking to the temporal periodicity of the amplitude-modulated
envelope, which underlies the perception of musical harmony, was
also more precise in musicians than nonmusicians. Neural enhancements
were strongly correlated with years of musical training, and our
findings, therefore, underscore the role that long-term experience
with music plays in shaping auditory sensory encoding.
