The article analyses Miloslav Kabeláč’s op. 50 (1965), the first of the series of his most mature works In some way, words play an essential role in all these works by introducing great humanistic and philosophical subjects. Words represent substance sui generis, and enter the composition as an autonomous form (contact with such substance matures the long thought compositional concepts, together with Kabeláč’s tectonically combinatory thinking). The analysis of op. 50 focuses in detail on the key relationship between music and words. It seems that the space, in which both components meet is in the form of a litany. In its juxtaposition with bi-polar format conception (based on two contrasting sound platforms – drama and reconciliation), and with regards to the title of the composition Eufemias Mysterion (The Mystery of Silence), it could be seen as a specific type of expression, a ritual and an initiation of space.
