THE THIRD RONDO-FORM.
In this form of composition there are three digressions from the Principal theme.

But, in order to avert the excess of variety, so imminent in a design of such length, the digressions are so planned that _the third one corresponds to the first_.

That is, there are here again only two Subordinate themes (as in the Second Rondo-form), which alternate with each other, so that the succession of thematic factors is as follows: Principal Theme; 1st Subordinate Theme; Principal Theme; 2d Subordinate Theme; Principal Theme; 1st Subordinate Theme; Principal Theme; and coda.
It will be observed that this arrangement is another confirmation and embodiment of the Three-Part (tripartite) form, with its "recurrence of the first section," magnified into larger proportions than any examples thus far seen.

The three portions are called, _Divisions_.
