Woodwinds performing patterns of accompaniment are very common through the orchestral literature. This section has the benefit, as do the strings, that they can fit below quite soft melodies due to their ability to perform pretty soft, almost at the low level of the strings.
Something to take into account is that, unlike the strings, the woodwinds could cause more fatigue in the listener’s ears when used for long stretches, especially if we don’t change their pattern. For that reason, and because it also causes more fatigue on the player than in a string performer, woodwinds should be used as accompaniment mostly alternating with other sections of the orchestra, or changing between sub-sections of the woodwind section.
