Music for children is perhaps a composer's most subtle challenge. If it is to last, it must both delight the child and beguile the adult. It, thus, must deal with innocence in a sophisticated way. Wikipedia says:

A Table Canon is a retrograde and inverse Canon meant to be placed on a table in between two musicians who both read the same line of music in opposite directions. Seeing that both parts are included in each single line, a second line is not needed."

Used mostly, but not widely, in the renaissance, tables canons were considered, even then, as parlor tricks, and as they are difficult to write, fell out of use. However, the device remains a part of the vocabulary of counterpoint, and "table" now references the device itself, and not furniture. In lieu of the table, my canons are fully written out.

The "Dodo Titite" theme, and only its first four measures, appears in the first canon, but its rhythmic elements are used in both. As the canons are played consecutively, without interruption, they together form a single composition.
