Romanian tenor Vasile Moldoveanu, a native of Konstanza, where he was born on 6 October 1935, studied voice in his natal city at the Ciprian Porumbescu Conservatory, under the tutorship of Constantin Badescu and Madame Costescu. He debuted at the age of 21 at the National Opera of Bucuresti in 1966, in the role of Rinuccio in Puccini's Gianni Schicchi. During the first years of his career he sang in Romania, but was soon engaged for guest appearances at the operas of Lüttich (Germany), Helsinki (Finland), La Monnaie in Brüxelles, Barcelona's Liceu, as well as appearances at festivals in Athens, Amsterdam, Dresden, Köln and Frankfurt. In 1972 he appeared for the first time at the Stuttgart Staatsoper as Edgardo in Lucia di Lammermoor and from 1976 at the Münchener Staatsoper (Rodolfo and the Duke) and the Wiener Staatsoper (Alfredo). In 1977 he was engaged at the operas of Berlin and Chicago and in 1978 at the state opera of Hamburg in Don Carlo.

His Met debut came in 1979 with Pinkerton in Madama Butterfly. Here he received a certain acclaim, particularly in Don Carlo (1980), Il Tabarro (1981) and Simon Boccanegra (1984). He also sang the roles of Enrico in I Vespri Siciliani, Turiddu in Cavalleria Rusticana and Des Grieux in Puccini's Manon Lescaut. In 1979 he also appeared for the first time at London's Covent Garden, where he sang Don Carlo.

In the 1980s and the 1990s he had a busy schedule in above all Germany, singing regularly in Stuttgart. He was also seen in Zürich in 1980 in Attila, in Monte Carlo, where he resided at the time, in Lucia di Lammermoor (1982), at the Teatro Regio of Parma in Don Carlo and the Caracalla in Rome in Turandot (1986). In 1988 he sang the role of Ramirez in La Fanciulla del West at the Nice opera, Cavaradossi in Marseille in 1990, as well as Pinkerton in Roma.

Moldoveanu was at times criticised for having "three voices,"¹ i.e., there was a difference in tone and timbre between his bottom, middle and top, a shift that could sometimes be heard to take place. He had nonetheless an exciting middle and a ringing, full-bodied upper register. His recorded legacy is scarce, but two recital LPs were once available from Intercord, released in 1976 and 1978 respectively.
