On how to sing
the frog school and the skylark school
This is a beautiful haiku in itself, although it does gain added point from the fact that its author Shiki had founded what was sometimes called the “Cuckoo school”.
Therefore this poem also refers to the differences between Basho’s school and Shiki’s school.
