Quantum mechanical systems exist as superpositions of complementary states that collapse to classical, concrete states upon becoming entangled with the measurement apparatus of observer-participants. A musical composition and its performance constitute a quantum system. Historically, conventional musical notation has presented the appearance of a composition as a deterministic, concrete entity,...

This article presents and discusses a long-term repeated-immersion research process that explores meaning allocated to an episode of 50 seconds of music improvisation in early neurosurgical rehabilitation by a teenage boy with severe traumatic brain injury and his music therapist. The process began with the original therapy session in August 1994 and extends to the current time of writing in 20...

A computer program has been written which composes blues melodies to fit a given backing chord sequence. The program 1s compri sed of an analysis stage followed by a synthesis stage. The analysis stage takes blues tunes and produces zero, first and second order Markov transition tables coveri ng both pitches and rhythms. In order to capture the rel at ionship between harmony and melody, a set o...

Improvised acting is a viable technique to study human communication and to shed light into actors’ creativity. The USC CreativeIT database provides a novel bridge between the study of theatrical improvisation and human expressive behavior in dyadic interaction. The theoretical design of the database is based on the well-established improvisation technique of Active Analysis in order to provide...

In this paper, we aim to analyze the performance of some variants of the harmony search (HS) metaheuristic when solving systems of nonlinear equations through the global optimization of an appropriate merit function. The HS metaheuristic draws its inspiration from an artistic process, the improvisation process of musicians seeking a wonderful harmony. A new differential best HS algorithm, based...
