Select the option that can be used as a one-word substitute for the given group of words.
Consonance of sounds.

The correct answer is Symphony.

Let's analyze the given phrase and examine the meanings of all the options to understand why "Symphony" is the correct one-word substitute:
1. Symphony: A symphony is an elaborate musical composition for a full orchestra, but the word itself originates from Greek roots meaning "consonance of sounds" or "sounding together" (syn- meaning "together" and phone meaning "sound"). In a broader literary and phonetic sense, it refers to the harmonious agreement or consonance of sounds.
2. Troupe: This refers to a group of actors, singers, or dancers who travel and perform together. It is unrelated to the consonance of sounds.
3. Woodwinds: This is a family of musical instruments (such as flutes, clarinets, oboes, and bassoons) that are played by blowing air across a mouthpiece or reed. It does not refer to the concept of consonance.
4. Orchestration: This is the arrangement or writing of music for performance by an orchestra. While it involves organizing sounds, the direct term for the actual "consonance of sounds" is "symphony".

Therefore, "Symphony" is the most appropriate one-word substitute.
