Summary
| Description |
English: One of Bach's two-part canons from The Musical Offering. This one is commonly called the "Crab Canon", especially after it was popularized in Douglas Hofstadter's 1979 book, "Gödel, Escher, Bach".
The green part is the blue part backwards, which makes the entire piece into a palindrome except for the fact that the parts switch roles. Visualized using Synthesia. |
