Witold Szalonek Sonority and its form shaping powers Theses: 1. Music is a phenomenon in the field of communication. 2. Music is an asemantic language/code, through which Man - a social creature situated on the path of evolution and already having developed "reflective conscionsness" - expresses and perceires all for his human being indispensable contents, which can be communicated only in terms of aural means ("by that what is audible"). 3. Conditioned by the function and structure of Man central nervous system and hearing apparatus, all by means of this language created forms of musical statement are: antiadaptive construcions of sonic stimul which manifest themselves within the element of time. Emphasis on sonority is a tendency in the music of the second half of the fourteenth century, in which values of timbre are usedas a fundamental and autonomous means of expression. 4. The possibility of perceiving various kinds of constructions of sonic stimuli, permits an equally varied range of sound parameters to which the "principle of repetition" can be applied: A. Timbre, determined by:  a. characteristics of the soundgenerater employed  b. charakteristics of articulation  c. pitch, which can be organized horizontally (melody), or vertically in combinations of psychological experience B. Volume, as a phisical or as a psychological experience C. Division of time, which can manifest itself eighter in structured rhythm,or in arythmic sonic-space forms. 5. Independtly of the degree of complexity of inner sonic parameters (i.e., timbre) , the greater the connections and interdependence of sonic structures in a work, the more disciplined and clear will be its form and ultimately its statement. 6. The level of intertwining dependencies, conditionalities and relationship of sound parameters, which contribute to the macro-structur of a musical work,can be perceired consciously as well as subconsciously by the listener. 7. Because:  a) the sonic stimuli" (as acoustic phenomenon),  b) their generators (the performing apparatus and  c)the receiver (the human nervous system fitted out in the hearing mechanism) are all governed by the laws of nature,the development of the language of music and its progress from simple to more complex forms is a result of this unique interdependence.(This development is dependendent on Man¹s discoveries of natural law an reflects the level of the intelectual and spiritual progress of various civilizations and cultures.) This process takes place exclusively in the physical aspect of musical language and its resulting forms which functions as a tool of communication, that is steadily being "modernized". In contrast, the aspect of musical contents has always afforded and with always afford evoling Man the possibility of expressing universal and infinite values. 8. "New Music (of the "white Western world") is since Debussy determined by the universalistic fendencies which are intergrating the intellectual scope and aesthetic treasures of non-European cultures on one hand and the achievements in the field of electroacoustical apparatus on the other hand.
