But from the beginning of bar No. 2 it is necessary to make only the simple gestures:—

Once entered upon the combination, the little allegro in 3/8, of which a whole bar represents one-third, or one beat of that of the minuetto, and the other allegro in 2/4, of which a whole bar represents two-thirds, or two beats, correspond with each other and with the principal theme; while the whole proceeds without the slightest confusion. All that is requisite is to make them come in properly.
