found: New Grove dict. of mus. online, Mar. 11, 2013(In its narrow meaning, a form of Melodrama which features one character, sometimes with chorus, using speech in alternation with short passages of music, or sometimes speaking over music. Simultaneously with melodrama, the initial enthusiasm for monodrama occurred chiefly in Germany during the 1770s and 80s, and the two terms are often used interchangeably, since many of the early melodramas had only one character on stage at a time...In modern times, the term has lost its exclusive association with the combination of speech and music characteristic of melodrama and is most often used as a synonym for a one-character opera, as in Schoenberg's Erwartung (1909) and Poulenc's La voix humaine (1958); as a non-staged dramatic work for singer and orchestra, as in Poulenc's La dame de Monte Carlo (1961), Floyd's Flower and Hawk (1972), Rochberg's Phaedra (1973--4), J.E. Ivey's Testament of Eve (1976) and Peter Maxwell Davies's The Medium (1981); or even as a purely instrumental work.)
