Abstract: The study of auditory and music cognition provides opportunities to explore general cognitive mechanisms in a specific, highly structured domain. We discuss two problems with implications for other domains of perception: the self-organization of perceptual categories and invariant pattern recognition. The perceptual category we consider is the octave. We show how general principles of self-organization operating on a cochlear spectral representation can yield octave categories. The example of invariant pattern recognition we consider is the recognition of invariant frequency patterns transformed to different absolute frequencies. We suggest a system that uses pitch or musical key to map tones into a pitch-invariant format.
