Discussions of operatic dramaturgy lie at the intersection of musicology, theater studies, and to some extent also literary criticism. Perhaps this is why efforts toward a theoretical grasp of issues related to operatic dramaturgy appeared relatively late on the international scene, not until the 1960s. The most influential conception of the evolution of operatic dramaturgy and libretto construction was created in German musicology, especially in the works of Carl Dahlhaus. In his concepts, but also in the works of authors of the younger generation, such as Albert Gier, we naturally find continuity with the tradition of German literary and theater studies, which are represented by Volker Klotz3 and Peter Szondi.4 In recent decades these interdisciplinary concepts have significantly inspired even Anglophone musicology, which was previously oriented primarily toward the purely musical analysis of operatic works. It can only be regretted that the pioneering work of Czech aesthetician Otakar Zich during the interwar period did not enter into the international discourse surrounding such topics.5 It is in the light of these interdisciplinary concepts that we will look at the issues pertaining to Janáček's operatic musicalization of Čapek's Věc Makropulos (The Makropulos Case, or The Makropulos Affair) and at the issue of the effect of traditional operatic aesthetic norms and principles in modern forms of opera of the 1920s.

Leoš Janáček first encountered Čapek's play in December of 1922, thus shortly after its premiere. He soon asked Čapek for permission to create a libretto based on the theatrical drama. Čapek agreed without any objections that Janáček could manipulate the work according to the composer's own discretion, even though Čapek considered the genre of conversational comedy to be unsuitable for operatic treatment.6 He was not interested in collaborating with Janáček on the libretto, as he regarded the musicalization of the play a lost cause from start.7 Janáček began work on the opera in November 1923 and finished it, after some revisions, in December 1925. A year later TheMakropulos Case opera had its premiere in Brno. It was first performed in Prague on 1 March 1928; its first foreign performance came in Frankfurt am Main in February 1929, thus six months after Janáček's death.
