What is unaccompanied choral music?

Unaccompanied choral music refers to vocal compositions performed by a choir without instrumental accompaniment. This genre often emphasizes the harmony and texture of the human voice, allowing for intricate vocal interactions and rich sonorities. It can encompass a variety of styles, including sacred and secular works, and is commonly found in genres like Renaissance polyphony and contemporary choral compositions. The absence of instruments places greater focus on the singers' interpretation and vocal expression.
