How did Baroque music increase the importance of the individual performer?

During the Baroque period (c. 1600–1750), the importance of the individual performer increased significantly as the musical landscape shifted away from the highly structured, equal-voiced polyphony of the Renaissance toward a style that emphasized solo expression and instrumental virtuosity.12

Several key developments facilitated this rise in performer agency:

• The Monodic Revolution: The emergence of monody—a style featuring a single vocal melody supported by a basso continuo—placed the soloist at the center of the musical experience. Because the accompaniment was often only partially written out, performers were granted the freedom to improvise harmonies and embellishments, effectively reiterating their creative rights.13
• Rise of Instrumental Idioms: As instrumental music gained independence from vocal models, composers began to exploit the specific capabilities of instruments. This led to the emergence of virtuosity, particularly among keyboard and string players, who utilized spectacular techniques to showcase their individual skill.14
• Ornamentation and Improvisation: Performers were expected to add ornamentation to melodies to heighten emotional expression. In many cases, composers provided only a skeleton of the music, leaving the performer to fill in florid embellishments, which allowed for a highly personalized interpretation of the work.5
• The Solo Concerto: The evolution of the concerto further elevated the individual. While early forms like the concerto grosso relied on the interplay between groups of players, the later shift toward the solo concerto established the soloist as a self-sufficient, virtuosic adversary to the orchestra.46
