Recent studies have shown that basic properties of auditory system can be accounted for by sparse coding or Independent Component Analysis (ICA) for natural sounds. Meanwhile, Kadia and Wang [1] have reported that harmonic relations appear in frequencies of modulatory peaks of neurons in primary auditory cortex of awake primates, using pure- and two-tone paradigm. This study shows that the complex harmonic relations emerge from a frequency-domain sparse code of highly harmonic sound, piano performance. The result implies that brain conforms, across various stages of sensory information processing, to information theoretic principle.
