The perception of interleaved melodies

摘要: Abstract If the notes of two melodies whose pitch ranges do not overlap are interleaved in time so that successive tones come from different melodies, resulting sequence is perceptually divided into groups correspond to melodies. Such “melodic fission” demonstrates perceptual grouping based on alone, and has been used extensively music. Experiment I showed identification pairs familiar possible if their overlap, but difficult otherwise. A short-term recognition-memory paradigm (Expt II) interleaving a “background” melody with an unfamiliar interferes same-different judgments regardless separation ranges, range attenuates interference effect. When listeners can overcome effect recognize target prespecified, thereby permitting them search actively for it III). But familiarity or prespecification background appears reduce its interfering effects concerning IV).
