2 bifolios. Written in purple and black ink. Paper: fol. 1: 16 staves; fol. 2: 12 staves. Title at the bottom of the page: "Thema med 14 Variationer, skrevne for Johan Peter Hartmann / Nærum 5/8 81 / JPEH." (Theme with 14 Variations, Written for Johan Peter Hartmann). Johan Peter was Hartmann's eight-year old grandson. On a couple of empty staves the latter has practiced the notation of scales in pencil. On p. 2 a two-part piece without title, crossed out, apparently also intended for use in a pedagogical context. (HartW 124). The two bifolios have been cut apart and glued together again in a new way, thereby changing the order of the variations. Furthermore, some of the original numbers of the variations have been crossed out and new numbers added in pencil.
