Note that these examples are modeled after the English Baroque practice of implementing a ritornello variation (or a variation that is used as a refrain - see the Grounds of Henry Purcell). This is an interesting alternative to the paired variation model that is more commonly found in the German Baroque (see Buxtedhude's Chaconne in e minor). Student composers are encouraged to explore both models.
AUDIO and MIDI files can be listened to on this page or downloaded separately here.
This first example incorporates a tonicization to the supertonic key region within the course of a variation.
The second example integrates a modulation (to the relative minor in this case) through a modification of the basso ostinato.
