Here's a crab and palindrome canon in four voices (violin, viola, oboe and bassoon).
Crab canon means: there's a theme that plays against itself in retrograde (i.e. itself played backwards).
Palindrome canon means: if you play this piece backwards you get exactly the same piece again (barring instrument assignments).
The graphics depict how this piece is built up. This is by no means the only possible form for a crab canon. Score is composed/calculated using lilypond (see lilypond.org ) - something like 20% composing, 80% calculation.
Tutorial on how to systematically write a piece like this (including the full score for this piece) has been published on my blog: a-touch-of-music.blogspot.com/2012/08/how-to-write-crab-canon.html.
