Musicians recognize pitch as having two dimensions. On the keyboard, these are illustrated by octave and cycle of notes within octave. In perception, dimensions referred to height chroma, respectively. Pitch chroma provides a basis for presenting acoustic patterns (melodies) that do not depend on particular sound source. contrast, segregation into streams separate sources. This paper reports functional magnetic resonance experiment designed search distinct mappings types change in human brain. The results show is specifically represented anterior primary auditory cortex, whereas posterior cortex. We propose tracking information occurs areas, objects (a crucial aspect scene analysis) depends areas.
