The author suggest that a parallel between psychoanalytical concepts and musical creativity can enhance our understanding of communication in psychotic states of mind. He points at some potential approaches to music in clinical practice and concentrates on musical expression of psychotic part of personality. To illustrate his ideas author makes references to work of avant-garde artist, Diamanda Galás. Main issues of this paper are: 1) predominant communication pathway in the case of the psychotic process is, above all, the emotional response evoked in the recipient; 2) crude transmission of primaeval emotion requires expression in equally crude, primal form; 3) the possibility of expression - even when primitive, but taken up in order to communicate - provides hope for an experience shared with another person. Author concludes his paper with artist's comments on ideas presented.
