The fundamental activity in this course is observation. Having arrived at a formative idea for a composition by means of a close analysis of a generative source, we begin describing that idea by any of several means (for example, a score, a performance or a sound generator), and making sense of that idea in sound. At the discretion of the instructor, students work with acoustic instruments, digital music technology, or both. Offered occasionally. Prerequisites: MUS 200/201 and MUS 220. May be repeated for credit when course content varies.
