Expected learning outcomes
At the end of the course, set in an interdisciplinary way, the student will understand the music as an art and a science, basic techniques common to mathematics, geometry, physics and computer science. Based on these requirements, the student will be able to identify the principal styles and forms that embody the history of music in contemporary, historical perspective through examples of composers from which emerge technological elements. The student will learn the scientific-technical fundamentals (physical and acoustic) that are the basis of sound production and will also learn the ways of interaction between music and modern technology in a historical, mathematical, physical and technical sense.
The course aims to provide knowledge on the historical evolution of modern music, in interaction with its basic nature of mathematics, scientific and technological development. Its focus on the evolution of the modern history of western classical music will be developed in chronological perspective along the twentieth century and will review composers, styles and significant works, taking into account some basic kinds of work under the artistic production. It will also show how the addition of new technologies has changed the creativity, the music offering new combinations of resources and other tools or machines. The musicians and the different areas will be introduced by providing some preliminary information, understood as an ear training in listening through practical demonstrations on the different styles and meanings of composing.
The course will also provide the elements of musical acoustics and of the physics of classical (i.e., non-electronic) musical instruments. To this aim, the physics of sound will be briefly developed at an introductory level, with reference to the production, propagation and duration of sounds in closed spaces, and to the possible partitions of the range of audible sound frequencies, with emphasis on the differences existing among alternative criteria for the partition of the octave (i.e., different temperaments).
The elementary physical processes at the basis of the operation of the main classes of musical instruments will be elucidated. Finally, the existing and existed relationships between building architecture and musical architecture will be examined, in order to show the historical influence that the development of technology has exerted on the development of the musical expression.
To highlight some links between mathematics and music, the course will present different music from a mathematical perspective, focusing on their structural aspects; geometrical transformations and other mathematical tools will be used. Furthermore, different mathematical algorithms generating music will be examined, together with some music composed using the described mathematical methods.
Finally, it will be analyzed how the development of electronics and computer science has deeply modified the way music is generated, processed, transmitted and consumed. The new techniques include music synthesis via digital machines, spatial sound processing, music signal compression, Internet transmission, restoration of historical recordings. To illustrate the role of technology in modern music, the principles behind the main audio coding and synthesis techniques, as well as the main languages for synthetic description, i.e., MIDI, will be discussed.
