Helga Dernesch is an Austrian opera singer from Vienna who began her professional career in the early 1960s, first performing in German-language opera houses and initially singing mezzo-soprano repertoire before moving into soprano roles. Her repertoire ranged from Mozart and contemporary works to the heavier Germanic roles of Wagner and Strauss, marking an evolution from lyric and mezzo parts into dramatic soprano territory that reflects mid-20th-century trends in German and Austrian opera.
