Phrasing influences the recognition of melodies

One critical step in the processing of complex auditory information (i.e., language and music) involves organizing such information into hierarchical units, such as phrases. In this study, musically trained and untrained listeners' recognition memory for short, naturalistic melodies varying in their phrase structure was tested. For musically trained subjects, memory for information preceding a phrase boundary was disrupted and memory for information subsequent to a phrase boundary was enhanced relative to memory in similar temporal locations for excerpts not containing a phrase boundary. Musically untrained listeners, in contrast, showed no such differences as a function of the phrasing of the melody. These findings conform with previous results in both psycholinguistics and musical cognition and suggest that the phrase serves as a functional unit in musical processing, guiding the parsing of musical sequences during perception, along with the structuring of memory for musical passages.
