**Open questions about this gap**:

1. When does the first gap appear along the 202 notations? …why?

4. *Starry, Starry Night* by Don McLean captures this gap and its quantum indeterminacy. Perfection would be stifling it it did not have room for creativity and loss and even despair. In some camps McLean’s song is also known as *Vincent* (as in Van Gogh).
