As a general rule, brass instruments lack the capacity to express passion or geniality. Phrases charged with these sentiments become sickly and insipid when confided to the brass. Energetic power, free or restrained, simplicity and eloquence constitute the valuable qualities of this group.
Brass in unison, in octaves, thirds and sixths.
As, from its very nature, the brass is not called upon to realise a wide range of expression, kindred instruments of one group may be employed solo, as well as in unison. The combination of 3 trombones or 4 horns in unison is frequently met with, and produces extreme power and resonance of tone.
Examples:
Snegourotchka 5—4 Horns (cf. [Ex. 15]).
Snegourotchka 199—4 Horns and 2 Trumpets.
Sadko 175—1, 2, 3 Trumpets.
