The four players build a machine, in which there is movement (see the regular Machine), but in which the most important part is that everyone sings their own line of text. If the machine has four parts, someone steps out and sings a couplet. The other three keep singing their sentences. Afterwards the singer steps back into the machine and keeps singing their sentence, perhaps changed due to the couplet. Another player can then also step out of the machine. In principle everyone sings one couplet, but this can be more or less.
