What was a significant characteristic of "Revenge" as an arietta?

In the context of "Revenge" as an arietta, the characteristic that stands out is its provision for a dialogue between instruments and voice. This interaction is fundamental to the arietta form, allowing for a rich exchange that enhances the expressiveness of the piece. The instruments support and complement the vocal line, creating a conversation-like quality that is often found in operatic and vocal music. This interplay underscores the emotional content and narrative of the music, bringing depth to the performance.

The other options do not specifically align with the defining features of "Revenge" as an arietta. For instance, while some ariettas may involve orchestration, not all require a full orchestra; they can be performed with smaller ensembles as well. Multiple singers may be a feature of certain compositions, but ariettas can also effectively showcase a single voice, which is generally the case with "Revenge." Lastly, the requirement for a large audience is not a defining characteristic of an arietta. Instead, the focus is typically on the intimate and engaging communication between the singer and the accompanying instruments.
