As implied by its title, this arrangement was based off my Crab Canon (aka. Canon Cancrizans) a 3 in C minor ( • Three-voice Crab Canon in B minor.):
Since its initial publication, it has been transported one half step upwards to accomodate for the ranges of the instruments involved in this double trio, with the full realization played by the Continuo harpsichord part (which may be omitted entirely on account of the extremely wide intervals between voices in certain invertible configuartions making it rather difficult to play).
Enjoy!
