The mezzo soprano is a middle range voice for females and the most common too. it is an intermediate voice which lies between the soprano voice and the contralto voice overlapping both of them. the tessitura of a mezzo soprano is lower than that of a soprano and higher than that of a contralto. General range is A3-A5. They tend to be slighly higher or lower. Some may sing the same range with sopranos due to developed vocal ability to the point that you might not be able to tell the difference. An example is Ledisi. She sings a b flat 5 even better and as frequent as most sopranos.
