Wind and brass instruments may be combined by the method of placing a chord in one timbre side by side with the same chord in another timbre, or by any of the three methods already described: overlaying, crossing and enclosure of parts.

1. In unison (juxtaposition or contrast of tone qualities).

This class of combination possesses the same features as combinations in the melodic line (cf. [Chap. II]). Wood-wind reinforces the brass, softens it and reduces its characteristic qualities. Arrangements such as the following are possible:

2 Trumpets + 2 Fl.;
3 Trumpets + 3 Fl.;		2 Trumpets + 2 Ob.;
3 Trumpets + 3 Ob.;		2 Trumpets + 2 Cl.
3 Trumpets + 3 Cl.
