Vocal range refers to the range of pitches that a person's voice can produce, from the lowest note to the highest note. It is typically measured in octaves and can vary significantly among individuals. Factors such as age, gender, and vocal training can influence a person's vocal range. Different types of singers, such as sopranos, tenors, and basses, have specific vocal ranges that categorize their voices. Understanding vocal range is important for singers and musicians, as it helps them choose appropriate songs and techniques that suit their unique voice capabilities.
