Which of the following composers is not typically associated with the creation of the mass?

Stravinsky is not typically associated with the creation of the mass in the same way as the other composers listed. While Stravinsky did compose works that were inspired by sacred themes, such as "Pulcinella" and "Symphony of Psalms," he is more renowned for his contributions to ballet and modern orchestral music, particularly in the context of 20th-century innovations in style and technique.

In contrast, Mozart, Beethoven, and Wagner each composed significant works within the liturgical genre of the mass. Mozart wrote various masses, including the famous "Requiem" and several settings of the ordinary mass. Beethoven composed the "Missa Solemnis," a monumental work that reflects his deep engagement with the spiritual and musical traditions. Wagner, although known primarily for his operas, also created significant pieces related to the mass, incorporating them into his artistic vision.

Due to Stravinsky's focus on different musical forms and styles, especially in the context of early and mid-20th-century music, he stands apart from this tradition, leading to the conclusion that he is the composer least associated with the traditional mass form.
