A catch is a type of round, a musical composition in which two or more voices (usually at least three) repeatedly sing the same melody, beginning at different times. Often ending with a meaningful lyric sung by the successive voices, in this case ” dock – tore – Oi – whales ”
It’s a bit like compiling a crossword puzzle, you need to know the result before you begin to put it together.
