How does Verdi use orchestration and harmony to show emotion in Otello?

In his opera Otello, Giuseppe Verdi demonstrates a masterful command of musical components to convey complex human emotions. By the time he composed this work, Verdi had achieved full control over the dramatic and musical elements of opera, utilizing nuanced orchestration and harmony to underscore character development and emotional depth.1

Rather than relying on traditional, stand-alone arias, Verdi worked with librettist Arrigo Boito to create a seamless musical-dramatic experience. This approach allowed him the flexibility to weave music and text together, ensuring that the orchestral and harmonic textures directly support the unfolding psychological drama of the characters. This sophisticated integration of music and emotion in his later works has often drawn comparisons to the dramatic techniques of Richard Wagner, though the two composers occupied distinct operatic realms.1
