TLDR
An artificial neural network was trained to classify musical chords into four categoriesindependent of musical key and it was found that the first layer of connection weights in the network converted the local representations of input notes into distributed representations that could be described in musical terms as circles of major thirds and on circles ofmajor seconds.
Abstract
An artificial neural network was trained to classify musical chords into four categories—major, dominant seventh, minor, or diminished seventh—independent of musical key. After training, the internal structure of the network was analyzed in order to determine the representations that the network was using to classify chords. It was found that the first layer of connection weights in the network converted the local represen tations of input notes into distributed representations that could be described in musical terms as circles of major thirds and on circles of major seconds. Hidden units then were able to use this representation to organize stimuli geometrically into a simple space that was easily partitioned by output units to classify the stimuli. This illustrates one potential contribution of artificial neural networks to cognitive informatics: the discovery of novel forms of representation in systems that can accomplish intelligent tasks.

Knowledge, Truth, and Values in Computer Science

TL;DR: It is argued (Colburn & Shute, 2007), however, that the nature of computer science abstraction lies in the modeling of interaction patterns, while thenature of mathematical abstraction lies at least as much in the modeled of inference structures.

A Generative Theory of Tonal Music

TL;DR: Aboitiz et al. as discussed by the authors explored the relationships between language, music, and the brain by pursuing four key themes and the crosstalk among them: song and dance as a bridge between music and language; multiple levels of structure from brain to behavior to culture; the semantics of internal and external worlds and the role of emotion; and the evolution and development of language.
