"Most female voices tend to fall naturally into 4 principal categories: coloratura/lyric soprano, dramatic soprano, mezzo-soprano, and contralto. The light soprano usually sings high, florid music; the dramatic soprano sings high stentorian phrases; the mezzo sings mostly in the middle register; the contralto, mostly in the lower register. Occasionally, a phenomenal singer comes along who can encompass every aspect of vocal writing for the female voice." - Geoffrey S. RiggsIn the 20th century, the only singer to fill this void was Maria Callas, a rare soprano sfogato in the lines of Giuditta Pasta, Isabella Colbran, Maria Malibran & Giuseppina Ronzi de Begnis. This video showcases Maria's enormous range, technical facility, agility, flexibility & dramatic power in singing the most difficult music ever written for the human voice.
