The soprano singing voice is the voice of children and the highest type of female voice with vocal range that typically lies between "middle C" (C4) and "high C" (C6) The soprano voice (unlike the mezzo-soprano voice) is stronger in the head register than the chest register, resulting in a bright and ringing tone. Some sopranos can sing one or more octaves above high C using the whistle register. The following is a list of singers in country, popular music, jazz, classical crossover, and musical theatre who have been described as sopranos.
