 A spectacular example of contrapuntal ingenuity can be found in the double canon that forms the trio section of Mozart's Serenade for Wind Octet in C, K. 388.Here a pair of oboes and a pair of bassoons unfold two mirror canons at the same time.Erik Smith (1982, p.49) sees this as "a perfect example of Mozart's use of academic means, canon, inverted canon and mirror canon, to a purely musical and emotional end."
