ÒThe contemporary electronic music system has no predefined structure, but is initially a collection of possibilities – a set of variables or parameters such as pitch, loudness, space, timbre, etc., that exist in an undedicated state.Ó

                            -Alan Strange

 

There are two primary objectives in this course. The first is to instill a philosophy of exploration where the student is always asking, ÒWhat happens if I do this?Ó  Exploration and invention are crucial tools in the development of innovative software instruments and exciting compositions. The second objective is to become competent in the areas of music technology that are concerned with digital synthesis, digital signal processing, and algorithmic composition. The environment that will be used to explore these areas will be the SuperCollider 3 language, a powerful object-oriented programming language. SC3 will be used to create synthesis instruments, control interfaces, and compositions. Coursework will consist of daily assignments, larger scale projects, and a final project that will demonstrate a comprehensive understanding of the concepts and tools learned over the semester. There will also be several quizzes throughout the term.

 

Attendance: Due to the sensitive nature of the equipment, class attendance is vital to your understanding of how to operate the equipment safely. Each new technique covered in class brings about a new set of problems and procedures. You will be responsible for equipment damaged by negligence or ignorance because you missed instructions that were missed in class.

LEGAL STUFF:

If you qualify for accommodations because of a disability, please submit to me a letter from Disability Services (DS) early in the semester so that your needs may be addressed.  DS determines accommodations based on documented disabilities (303-492-8671, Willard 322, www.colorado.edu/sacs/disabilityservices)

 

Reasonable and appropriate accommodations will be made for those students who have conflicts between religious observance dates and course examinations and assignments. Please see me at the beginning of the semester to discuss any potential problems. (www.colorado.edu/policies/index.html)
