Which of the following composers is included in the list of mass composers alongside Josquin and Palestrina?

Verdi is included in the list of mass composers alongside Josquin and Palestrina because he composed a significant and well-regarded setting of the "Requiem Mass" known as "Messa da Requiem." This work is one of the most performed and studied pieces in the choral repertoire, showcasing Verdi's mastery in combining dramatic elements of opera with the liturgical form of the mass.

During the Renaissance and early Baroque periods, composers like Josquin and Palestrina were instrumental in establishing the mass as a prominent form within sacred music. Similarly, Verdi's contributions to the mass tradition, particularly through his Requiem, have solidified his place in the canon of mass composers. His work exemplifies how composers can adapt and evolve the mass form while still maintaining its spiritual and ceremonial significance.

In contrast, Weber, Hindemith, and Bernstein, although notable composers in their respective genres and periods, are not primarily recognized for their contributions to the traditional mass form in the same way that Verdi is. They have successes in opera, orchestral, or choral works but do not have significant mass compositions similar to Verdi's.
