Q: What does the title mean? A: A palindrome is something that's the same backward and forward. A canon (in music), is a piece in which one line is a duplicate of another (possibly with some modification). In this piece, there are two palindromes. The first palindrome is presented in two forms (once at the beginning of the piece and once at the end); these are inversions of each other (what's in the bass at the beginning is in the treble at the end and vice-versa). The second palindrome is a canon (the bass begins one measure after the treble). To fill the empty measure in the second palindrome, there is once extra measure added before the bass starts; this measure is reversed when it is reflected at the end of the treble part.
