Bach's "Prelude in H moll" BWV 544 and Chopin's "Scherzo" no.1
Barber's Adagio starts with an example of how Bach's transient harmony can be stretched out to make it into the main harmonic content of a piece. A converse example is found in Chopin's Scherzo. Chopin compressed Bach's dramatic chromatism into quick transient figurations.

If we slow down the quick harmonic changes in these bars, V 9 - VI - II 7m - V 7 - I - V, we obtain a musical text similar to Bach's longer and drawn-out harmony here,

and an even longer sequential passage at the end of the Prelude,

where the harmony is almost exactly as in Chopin: V 9 - VI - II 7 - V 9 - I - V 9

Chopin makes these harmonies - which are about as dissonant as in Bach - so quick that we barely hear them.
