Final answer:
The lead voice of a Bahamian rhyming spiritual is known as a Chanter, who lines out verses and sets the tone for the congregation to join in the singing.
Step-by-step explanation:
The lead voice of a Bahamian rhyming spiritual is known as a Chanter. This individual is crucial in setting the tone and pace of the hymn being sung, as they 'line out' the verses for the congregation. In the traditional context described, no instruments accompany the singing; instead, the entire congregation joins in after the chanter has begun. The result is a powerful and communal musical expression that is both elaborate and ornamentally rich. The term Rhymester could also be associated with the act of creating rhymes, but within the context of Bahamian spirituals, the term Chanter is commonly used to denote the lead vocal role that introduces and carries the song.
