There is lateralization involved with music. The pattern of a melody, along with minute distinctions between tones that are near each other in pitch, has been attributed to the right hemisphere. The left hemisphere, on the other hand, is involved in labeling a song or performer with the correct name. It is also involved in tracking the progress of a musical theme including information about keys and scales and the overall sense that the music makes. Being trained in music seems to shift the location of processing from the right to the left hemisphere, at least to some degree. (Sternberg, Barbara, PhD. Music & the Brain. p 16-17.
