The French horn is often used for lyrical melodies and sustained notes. It can also be used for solo passages, although these are less common than with other brass instruments. In some cases, the French horn may also be used for special effects, such as imitating the sound of a hunting horn or a cow's moo.
Overall, the French horn plays a valuable role in a brass band by adding depth and richness to the sound. Its mellow tone and versatility make it a useful addition to any brass ensemble.
