Adult male alto voice, either natural or falsetto. Some writers use the term only for the natural high tenor, preferring “male alto” for the falsetto voice. Like the castrato tradition, the countertenor developed as a result of the prohibition on women taking part in church choirs. Since the falsetto voice lacks power, it was little used in opera. The countertenor tradition was preserved in the English cathedral choir. Today it is again being widely cultivated internationally, primarily for Renaissance and Baroque music.
