Renata Tebaldi (pronounced [reˈnaːta teˈbaldi]; 1 February 1922 – 19 December 2004) was an Italian lirico-spinto soprano popular in the post-war period. Among the most beloved opera singers, she has been said to have possessed one of the most beautiful voices of the 20th century which was focused primarily on the verismo roles of the lyric and dramatic repertoires.[1][2][3]
