Which instrument represents the duck in "Peter and the Wolf"?

In "Peter and the Wolf," the duck is represented by the oboe. This choice is particularly effective because the oboe has a distinctive, slightly quacking sound that mirrors the characteristics often associated with a duck. The composer, Sergei Prokofiev, skillfully selected the oboe to convey the playful and somewhat gentle nature of the duck's character in the story. The timber and expressive capabilities of the oboe effectively bring the duck to life, making it easily recognizable within the orchestral narrative.

The other instruments, while they may have their unique qualities, do not capture the essence of the duck as effectively as the oboe does in this context. The flute, for instance, has a lighter and more airy sound, which does not align with the depiction of the duck. The tuba produces deep and resonant tones, making it suited for heavier, grounded characters, while the trumpet typically evokes bold, bright emotions and is more often associated with heroic themes. Thus, the choice of the oboe aligns perfectly with the portrayal of the duck in this musical tale.
