This is a canon at the sixth in {{time signature|2|2}} time. The canonic interplay in the upper voices features many [[Suspension (music)|suspensions]]. Commenting on the structure of the canons of the ''Goldberg Variations'', Glenn Gould cited this variation as the extreme example of "deliberate duality of motivic emphasis ... the canonic voices are called upon to sustain the [[Passacaglia|passacaille]] role which is capriciously abandoned by the bass." [[Nicholas Kenyon]] calls Variation 18 "an imperious, totally confident movement which must be among the most supremely logical pieces of music ever written, with the strict imitation to the half-bar providing ideal impetus and a sense of climax."<ref>[[Nicholas Kenyon|Kenyon, Nicholas]].
