The Shadow Cantata exchanges acoustic roles of choir and orchestra: the choir often performs vocalized melodies or sound effects, as if it were a single instrument or a choir of instruments, while the orchestra, through onomatopoeia of speech and recitation, encroaches upon the vocal domain. The intertwining and multi-layered nature of the cantata is based on a universal thematic idea presented by the choir. This is Goethe’s dedication to Faust, in Božo Vodušek’s translation. The excellent Slovenian adaptation, which does not lag behind the quality of the original, could be seen as a small cultural treasure. The Cantata of Shadows brings this to the attention of the Slovenian public once again. The text, which addresses life and cessation, the images of shadows and souls, is linked to the musical idea and postmodern expression of the Cantata of Shadows. The composition combines three distinct elements: orchestra, choir, and text (i.e., thought) — and maintains them in balance. The frequent use of aleatoric techniques and expanded vocal-instrumental techniques contributes to rhythmic and harmonic richness. In terms of using the choir as an instrument, which does not only convey the text of the song but also functions as an independent instrument and can at times be acoustically perceived as an instrument within the orchestra, the Cantata of Shadows represents a novelty in Slovenian musical expression.
