Complementary art is an artistic language and a new working method which has been developed by Andrej Kalinka and Milan Kozánek. The basic principle of such work is a thorough understanding of all participating artistic genres, forms and media (theater, dance, music, visual arts) as autonomous and equal partners. Before the creation of the piece and during its course, the possibility is open whether it is a performance, an exhibition or a concert. The resulting works are moving between these boundaries and often there are several separate outputs (performance, exhibition, etc.). Performers during the creative process go through different positions, functions, experiences, from the actor through the musician, dancer, artist, but not in the formal craft, but as a way of searching and discovering the essence of an particular medium in each individual. Through this experience, they continue to come to a natural, comprehensive expression. In the performance, it then acts as a living language in which the individual “sentences” are composed of “words”, the first of which can be denounced through music, followed by a gesture or a word, then music or an image, an object, etc. As a result, we get an anatomically complex organism that is not a fusion of several languages, but a language that is original. A very important part of the creative process of approaching in the complementary arts is to engage a particular performer with the component that has not yet been activated in him or only partially, e.g. if a performer originally comes from a musical environment, moving or working with text changes his way of accessing the original profession. Literally, such physical experience affects his elementary motor skills, reconsiders his current perception of art, and ultimately creates a new perspective and language. This is associated with personal, family, psychological, subconscious circumstances, which must be applied in the artistic and personal development of each participating performer. This experience then consequently becomes consciously or unconsciously an important part of the piece.
