Much of the remaining music follows or adapts these basic musical materials: we encounter passages in which a two-voiced texture elaborates an ornamented line that repeats some notes, and passages involving a more imitative texture following the first contrapuntal melody, and passages that riff upon the dotted-note motif and its rhythmic interest.
The conclusion of this lengthy fantasia shifts rhythmic meters twice and brings the virtuosic complexity of the inner voices to a peak of difficulty.
