Which of the following attributes were NOT associated with Wagner's operas?

Wagner's operas are characterized by a distinct style that diverges from traditional operatic forms, particularly regarding the use of arias and vocal ensembles. Unlike many composers of his time, who often incorporated tuneful arias designed for showcasing vocal prowess, Wagner's works feature a more integrated approach to music and drama. His compositions prioritize a seamless flow of music that supports the narrative, employing lengthy, continuous musical structures rather than standalone, catchy arias.

In contrast, the other attributes accurately reflect key elements of Wagner's operatic style. He is renowned for his use of extensive orchestras, which contribute to the rich and complex soundscapes that characterize his works. Wagner is also celebrated for his emphasis on dramatic narrative and character development, pushing the boundaries of storytelling in opera. Additionally, he developed the concept of the leitmotif, a recurring musical theme associated with specific characters or ideas, which further enhances the cohesion and depth of his narratives. These characteristics collectively distinguish Wagner's operas from those that focus on more traditional, tuneful arias and straightforward ensembles.
