The term "singing voice" refers to a person's ability or talent to produce musical sounds with their vocal cords through singing. It is an individual's unique sound and quality that comes from their physical attributes, such as range, tone, pitch, and timbre, as well as their training and technique. A good singing voice can be characterized by its clarity, power, and emotional expression, while a bad singing voice may lack these qualities or suffer from strain or discomfort when trying to sing.
