What is the genre classification of the Queen of the Night aria?

The Queen of the Night aria, known for its demanding vocal passages and dramatic content, is indeed classified as a solo song. This aria is performed by a single vocalist, typically in an operatic setting, and showcases the singer's vocal prowess and emotional expression. Its solo nature allows for a personal and intimate connection with the audience, which is a hallmark of operatic vocal performance.

In contrast, other genres listed such as orchestral symphonies, ballet performances, and choral pieces involve multiple performers or a focus on instrumental arrangements, which do not align with the distinct characteristics of a solo aria. The specific focus on a single voice in the Queen of the Night aria is what makes it a quintessential example of a solo song within the context of opera.
