Melody recognition survives transposition because pitch intervals, not absolute pitches, are encoded

Evidence

Most people easily recognise well known melodies even when they are transposed to a different key. The invariant property of transposed melodies is the preserved pitch ratio relationship between notes of the melody; i.e. pitch intervals of the melody remain the same despite changes in absolute pitch. For this reason, it is assumed that the ability to recognise pitch relationships (relative pitch perception) is rather robust and commonly found in the population. Recognition of preserved pitch interval patterns irrespective of absolute pitch is an auditory example of translation-invariant object perception (Kubovy and Van Valkenburg 2001 ; Griffiths and Warren 2004 ; Winkler et al. 2009 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5265
