Clementi's only contribution is the "Epitome of Counterpoint", which appeared in the beginning of Volume I. All other pieces were either transcribed or arranged by Clementi from the works of various composers.

WO 12	The Plough Boy, with Variations	Piano	1788	B♭ major	Keyboard	This work is doubtful, although some evidence exists that supports Clementi's authorship of the variations: the 1823 Catalogue of Vocal & Instrumental Music published by Clementi, Collard & Collard indicates the existence of "Plough Boy Clementi 1-0" in the section containing all of Clementi's known variations; although these variations were published anonymously by Longman & Broderip, Clementi had published Opp.16-21 with said company just before these variations appeared; and continental publishers sold these variations under Clementi's name, especially in tandem with WO 2 and WO 5. The theme originated in William Shield's opera The Farmer (1787).
