File:ChuGLTHX.jpg

Due Date

• parts 1 + 2 on web portfolio + uploaded to canvas: 2026.1.13 11:59:59pm, Tuesday
• in-class presentation of sound logo: 2026.1.14, Wednesday

Part 1: ChucKus

• construct two chuckus, according to the following specifications:
  • like a haiku, a chucku should contain exactly 3 lines of code (each less than 80 characters)
  • each chucku should generate sound
  • 5/7/5 pattern optional; do attend to the structural aesthetics of the code
  • check out one line chuck crazy to see similarly compact examples
  • the chuckus should be standalone (i.e., no external audio or chuck files)
  • (thanks to Chris + kijjaz for the idea)

Part 2: Design Your Sound Logo

• read "Design of the THX Deep Note" from Artful Design
• additional resources (code, score, Andy's personal account): THX Deep Note
• full instructions: Design Etude #4 from Artful Design
• design and create, using ChucK, your own sound logo
  • 30 seconds in duration
  • figure out what you are designing the logo for?
    • CCRMA?
    • yourself??
    • your cat???
    • an organization you belong to????
    • ???
• have a narrative (e.g., beginning, middle, end—or...)
• make it interesting
• experiment with have MANY INSTANCES (e.g., like saw voices in the THX Deep Note) that are both independently controlled but also obey an overall plan
• reference "A Few (Programmable) Parameters of Musical Sound" for ideas; you don't have use all of these, but do consider these
• (optional) add graphics/visualization of your sound logo using ChuGL
• have fun with it!

Part 3: Set up your web portfolio

• if you don't have one yet, create a CCRMA account
• read "Setting up your CCRMA homepage/220b website"
• your web portfolio should live at https://ccrma.stanford.edu/~YOURID/220b/

Deliverables

turn in all files by putting them in your 220b CCRMA web portfolio AND to Canvas (you will need a CCRMA account for this!)

• 1) this homework should live at https://ccrma.stanford.edu/~YOURID/220b/hw1
• 2) a separate .ck file for each chucku
• 3) title + clear description of the sound logo, who/what it's for, and how you deployed it
• 4) your .ck file(s) for your sound logo
• 5) an audio recording of your sound logo (e.g., hw1.mp3)
• 6) a short README text (readme.txt) file that:
  • conveys your ideas/comments in constructing each program
  • contains instructions on running your programs
  • describes any difficulties you encountered in the process
