Answer
Indeed, Violetta is not a commonly associated role with Renata Tebaldi. Tebaldi was renowned for her portrayal of dramatic and lyric roles in Italian opera, particularly those composed by Verdi and Puccini. Her signature roles include Desdemona in Otello, Aida in Aida, and Tosca in Tosca. While Tebaldi did perform Violetta in her early career, it was not a role she became particularly known for or frequently associated with.
