Information about Crab Canon
A crab canon is an arrangement of two things that are complementary and backward, similar to a palindrome. Originally it is a musical term for a kind of canon in which one line is reversed in time from the other (e.g. FABACEAE <=> EAECABAF). A famous example is found in J. S. Bach's A Musical Offering, which also contains a canon ("Quaerendo invenietis") combining retrogresion with inversion, i.e., the music is turned upside down by one player. The use of the term in non-musical contexts was popularized by Douglas Hofstadter in Gödel, Escher, Bach.
palindrome is a word, phrase, number or other sequence of units that has the property of reading the same in either direction (the adjustment of punctuation and spaces between words is generally permitted). Composing literature in palindromes is an example of constrained writing.
