Canon Engine (Strict 2-Voice)

Choose a generic interval of imitation (above/below) and the allowed resulting vertical intervals. The engine outputs the legal melodic intervals the dux can use (UP/DOWN/REPEAT) for a strict canon with a 1-note delay.

Candidate melodic intervals for the dux

This section acts as a filter. Select which melodic motions the dux is permitted to use (for example, stepwise only, or allowing larger leaps). The engine tests only the selected melodic intervals and then reports which of them produce your chosen allowed resulting vertical intervals.
