Step-by-step explanation:
To match the descriptive words or phrases with the different musical elements in the Gigue of Bach's Orchestral Suite No. 3, we first need to understand what each term represents. Harmony in music refers to how different notes and chords work together to produce a pleasing sound. In Bach's Gigue, you can hear harmony in the way the string section's notes complement each other, often following the rules of Baroque counterpoint.
Tempo is the speed or pace of a given piece. In the case of a gigue, which is a lively dance form, the tempo is typically fast and vibrant, driving the dance forward with energy.
Finally, performing forces pertain to the musicians and instruments used for the piece. In an orchestral suite like Bach's, this includes a variety of instruments such as strings, woodwinds, brass, and percussion, all tuned to work in concert. This could be exemplified by the orchestra members tuning their instruments to a common pitch before a performance.
