Music theory, music perception, music psychology, music aesthetics

Robert Jourdain's book "Music, the brain, and ecstasy" certainly mirrors the current state of research in the field of music perception in the brain, even despite Jourdain's journalistic simplifications and misinterpretations (e.g. the concept of the "grandmother-cell") have to be corrected. However, comparable to the field of language research, background theories about neural architectures that underly observable musical behaviour are highly vague and underestimated.

If we adopt the oppinion that architectural principles in the neo-cortex for most, if not all fields of knowledge are similar in structure and functioning and, since music and language perception clearly share some common properties (both use the acoustic channel), it seems natural to compare the phenomena and underlying neural structures in musics and linguistics.

This might open both fields to new insights and explanations.
