Christa Ludwig is acknowledged as one of the twentieth century’s most explorative and complete vocal artists. Her professional singing career spanned five decades and, as a star of the international operatic stage, she made roles as diverse as Rosina, Dorabella, Cherubino, Leonore, Amneris, Eboli, Kundry, Ortrud, Clytemnestra and the Marschallin her own, excelling in soprano, mezzo and coloratura mezzo repertoire. She also established her reputation as a fine lieder singer. The intimate auditorium of the magnificent neobaroque Volkstheater in Vienna was packed with a discerning and enthusiastic audience when Christa Ludwig gave a master class there. The young singers who took part – Valerij Serkin (tenor), Stella Grigorian (mezzo) and Marcus Pelz (baritone) – were all studying at an advanced level, with their sights set on finding success as professionals on the operatic stage. Christa Ludwig focused the time she spent with each singer on helping them to find the dramatic truth expressed in the aria of their choice and advising on how they could communicate this in their interpretation. With her guidance, their characterisations are seen to take on a new depth in just a short space of time. The master class focuses on Mozart and concludes with a performance extract featuring the young Christa Ludwig as Dorabella in Così fan tutte (1970).
