The cream is made in three color tones—the vanilla being the subdominant, as the chord is of subdominant character; the strawberry being the submediant, and the restful green the lowered supertonic or altered tone.”

In the opening Allegro the second subject occurs, by way of exception, in the major key of the submediant.

To be sure, Beethoven did invent the change to a lowered submediant in a succeeding movement.

A bright, though formal Scherzo, with a well-contrasted Trio in the key of the submediant, is followed by a melodious Andante and a graceful, showy Allegretto.
