In four sections: Imitative counterpoint in common meter with a characteristic hesitation step contrasted with a 3/4 version of the same subject played on a lighter registration. The playfulness is interrupted by a strong transition, and a different subject which appears recto and inversus (right- and up-side-down) is introduced on a bright registration, then finished off with the Pedal played an octave lower for a satisfying conclusion to this short excursion. [4:18] (a=460 Hz)
