paragraph_text: Vocal classifications
  
  Singers and the roles they play are classified by voice type, based on the tessitura, agility, power and timbre of their voices. Male singers can be classified by vocal range as bass, bass-baritone, baritone, baritenor, tenor and countertenor, and female singers as contralto, mezzo-soprano and soprano. (Men sometimes sing in the "female" vocal ranges, in which case they are termed sopranist or countertenor. The countertenor is commonly encountered in opera, sometimes singing parts written for castrati —men neutered at a young age specifically to give them a higher singing range.) Singers are then further classified by size—for instance, a soprano can be described as a lyric soprano, coloratura, soubrette, spinto, or dramatic soprano. These terms, although not fully describing a singing voice, associate the singer's voice with the roles most suitable to the singer's vocal characteristics.
  
  Yet another sub-classification can be made according to acting skills or requirements, for example the basso buffo who often must be a specialist in patter as well as a comic actor. This is carried out in detail in the Fach system of German speaking countries, where historically opera and spoken drama were often put on by the same repertory company.
  
  A particular singer's voice may change drastically over his or her lifetime, rarely reaching vocal maturity until the third decade, and sometimes not until middle age. Two French voice types, premiere dugazon and deuxieme dugazon, were named after successive stages in the career of Louise-Rosalie Lefebvre (Mme. Dugazon). Other terms originating in the star casting system of the Parisian theatres are baryton-martin and soprano falcon.
