Czerny's Op.12 Variations and ^5-^6

Carl Czerny's set of variations on D365n2 is in the bravura style but is obviously meant for domestic consumption, as he carefully and skillfully holds down the technical requirements to a level -- and with the kinds of figures -- that any reasonably well-trained pianist of the day could have managed. The piece consists of an introduction, theme, four variations, and lengthy coda.

The introduction seems to announce that the androgynous ^5 & ^6 will be its focus -- it's almost embarrassing in its profusion of figures:

As it turns out, although there are hints in the theme -- ^6-^5 over V and the expressive alteration of same to ^b6-^5 in the second strain -- Czerny steadfastly ignores the implications of his own introduction, downplaying or even eliminating the ^6-^5 in the variations. The final cadence of the fourth variation seems determined to erase all memory of the figure with an elongated scale, all that just before the sudden jump to bVI to announce the coda.

The score comes from IMSLP. It's a later edition marked as Wolfenbüttel: L. Holle, n.d., plate 178, but not dated. IMSLP also has a PDF scan of the original edition: Wien: S.A. Stemer und Comp, plate S. und C. 3377, but the scan quality is very poor.
