Exploratory Musicism: Ideas for Spontaneous Composition examines both music and musical composition, and the characteristics they share with science, mathematics and the natural world. Written for upper-division and graduate courses, the book shows students that music is part of an interdisciplinary collection of artistic modes of expression, and that these modes can be better understood in the context of what we observe in the real world. Using the book as a tool for extending the concept of music composition, students will discover new ways to connect music to more universal and organic constructions. As the rings of Saturn share similarities with how sound is organized, so does organic cell composition share similarities with music. As the mathematical Fibonacci sequence correlates to nature, so too can music be correlated to nature. In this book the way music is composed in real time (spontaneous composition) and music itself, are presented in a greater context. Exploratory Musicism leads students to the understanding that creativity is a vehicle through which we explore the evolution and interconnectedness of phenomena in our universe.
