Crab canon A crab canon (also known by the Latin form of the name, "canon cancrizans"; as well as "retrograde canon", "canon per recte et retro" or "canon per rectus et inversus") is an arrangement of two musical lines 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 played simultaneously with EAECABAF). A famous example is found in J. S. Bach's "The Musical Offering", which also contains a canon ("Quaerendo invenietis") combining retrogression with inversion, i.e., the music is turned upside down by one player, which is a table canon.
