Which of the following characteristics is NOT typical of an Art Song?

An Art Song, often referred to as a Lied in the context of German musical literature, is characterized by its intimate setting and is typically composed for solo voice with piano accompaniment. The essential relationship between the music and the text is central to its identity, which is emphasized in the correct characteristics of Art Songs.

The defining elements of an Art Song usually highlight the combination of a solo voice with piano, where the piano part enhances the narrative and emotional expression of the lyrics. While it's true that orchestral arrangements can exist, particularly in more elaborate interpretations of Art Songs, the standard form involves just a piano accompaniment. Therefore, the statement regarding vocal performances being accompanied by various instruments does not align with the core definition of an Art Song.

Furthermore, the other characteristics underscore the essence of what constitutes an Art Song: the focus on both the music and the text ensures that the emotional content conveyed is tightly interwoven, while the solo vocal performance emphasizes the personal expression of the singer. The orchestral accompaniment, while a possible variation, diverges from the traditional form and intent of the Art Song, which centers on the intimacy of a single voice and piano.
