As the title makes clear: this is a Chaconne in form of a canon. It is scored for four bass recorders and an optional sub-great as continuo. (If no such beast is available, there is a variation of the opening statement that outlines the harmonies.) This piece can be played as a solo with variations, or a canon with up to four voices.
Originally offered to my Patreon supporters, this is now for sale on Score Exchange.
