What characterizes a Baroque suite?

A Baroque suite is characterized by a collection of dances that typically share the same key. The fundamental structure of a suite includes a series of contrasting dance movements, each with its distinct character and tempo, but unified by the common tonal center. This key consistency creates a cohesive musical experience, allowing the pieces to flow together while still showcasing the diversity of dance styles.

Suites often include movements such as the Allemande, Courante, Sarabande, and Gigue, among others, each originating from different dance forms popular in the Baroque era. The emphasis on dance rhythms and styles paired with the shared key contributes significantly to the suite's identity. This is a hallmark of Baroque composition and distinguishes suites from other forms, such as those that may consist of unrelated pieces or move through different keys.

In contrast, the other options present characteristics that do not align with the fundamental definition of a Baroque suite. For example, a collection of songs in different languages does not pertain to the dance-centric nature of suites, while a series of dances in varying keys would lack the coherent tonal unity that typifies a Baroque suite. A solo instrumental work could describe various forms of music, but it doesn't specifically capture the essence of the suite format,
