This course blends Musical Acoustics, History of Science, an introduction to computer music, and (for some students) an introduction to 20th century music and non-Western music. Issues involving the relationships among technology, culture and society are examined and are important to discussions. There are no prerequisites for this class, but some knowledge of music and/or computers is extremely useful. Note: students enrolled in MU207 are entitled to use the facilities in the Studios for Integrated Media (SIM), in the Fine Arts building across the ring road. In addition, the Media Centre in the library also has music/audio software and hardware. NOTE: if you want to use the Max/MSP software at home (optional software used in this class) you can get it for your own use here:

Counselling Services - Counselling Services can help you make the most of your university experience.They offer free professional, confidential, inclusive support to currently registered UVic students. A note to remind you to take care of yourself. Do your best to maintain a healthy lifestyle this semester by eating well, exercising, getting enough sleep and taking some time to relax. This will help you achieve your goals and cope with stress. All of us benefit from support during times of struggle. You are not alone.

Health Services - University Health Services (UHS) provides a full service primary health clinic for students, and coordinates healthy student and campus initiatives. We encourage students to use UHS as their primary point of health care while at UVic. We are located at the Petersen Health Centre.

Centre for Accessible Learning - The CAL staff are available by appointment to assess specific needs, provide referrals and arrange appropriate accommodations . The sooner you let us know your needs the quicker we can assist you in achieving your learning goals in this course. 

Elders' Voices - The Office of Indigenous Academic and Community Engagement (IACE) has the privilege of assembling a group of Elders from local communities to guide students, staff, faculty and administration in Indigenous ways of knowing and being.

The extreme interdisciplinarity of music technology. An informal survey of the class to find relative backgrounds of students in Music, Mathematics, Computer Science, etc. What are digital media? All digital media are approximations of reality -- so what are the advantages? Geometric version of approximation of circle. The first music produced on a computer (at AT&T's Bell Labs). What does human evolution have to do with music?

Week 2 Sept 15          Reading: Chapt. 2 Periodicity, Pitch, and Waves

Oct 2 Paper preview/outline due

Week 5 Oct 6          Reading: Appendices A-F

Bach in equal temperament vs. "well-tempered" on the harpsichord
How to tune a harpsichord in Bach's temperament (as theorized by harpsichordist Bradley Lehman)

Perceptual coding (eg mp3 files). How does a computer make music? "No air molecules were disturbed in the making of this sound."
