You don’t need to know anything about composing music for this activity. In fact, this is all just a “thought experiment” in the making.
Either find yourself some blank online music paper or draw yourself a blank one on paper.
Then, get your Mozart on and start writing music. Use dots and lines to visually indicate the flow of your thought experiment song. (Need more? This is more than you probably need to know about music notation. Certainly, it is more than you need to know for this Daily Create).
Want to invent some new musical notations? Go ahead.
Bonus points for anyone who tries to play, and shares out, what they have written.
