2. 2 2 connecting Computer Science to Music and Art through interdisciplinary courses –synchronized vs. hybrid courses originally conceived to attract and retain CS majors by connecting theory to practice –but also exposes non-CS majors to higher levels of computing than typically seen in “GenEd” courses supported by NSF CISE CPATH connecting Computer Science to Music and Art through interdisciplinary courses –synchronized vs. hybrid courses originally conceived to attract and retain CS majors by connecting theory to practice –but also exposes non-CS majors to higher levels of computing than typically seen in “GenEd” courses supported by NSF CISE CPATH

3. 3 3 Sound Thinking: Goals of Original Course Must clearly deal approximately equally with both computing and music –GenEd Committee was adamant that Science majors must learn about music while Arts majors must learn about computing Not just sound... music –aesthetics as well as mechanics –encouraging creativity –allowing students to work with their own music Must clearly deal approximately equally with both computing and music –GenEd Committee was adamant that Science majors must learn about music while Arts majors must learn about computing Not just sound... music –aesthetics as well as mechanics –encouraging creativity –allowing students to work with their own music

4. 4 4 Sound Thinking: Add’l Goals of Revised Course Integrate music and CS theory more closely –create exercises and experiences where students can see the relationships more clearly Switch from web-based sound production using JavaScript to sound coding in Scratch –integrate Scratch throughout the course –basic tasks to generative music to live coding Create more course activities that can be replicated by others Integrate music and CS theory more closely –create exercises and experiences where students can see the relationships more clearly Switch from web-based sound production using JavaScript to sound coding in Scratch –integrate Scratch throughout the course –basic tasks to generative music to live coding Create more course activities that can be replicated by others

18. 18 Found Instruments Project: Music Methods Assignment Using only household object(s), create a musical “instrument” that can produce several pitches or timbres. Create a composition for your instrument. Devise a system of creative notation that others will be able to understand well enough to perform your composition without specific instruction from you. –Your system must not resemble standard musical notation in any way, shape, or form.

19. 19 Found Instruments Project: GUI Programming Assignment Create a computer program to implement one of the music students’ found instruments. Your program must be designed so that others can understand it well enough to create compositions without specific instruction from you.
