The paper presents an intonational analysis of several Romanian declarative contours by using a functional account of the prosodic words and phrases at the communicative act level. The functional prosodic words and phrases transform the corresponding word(s) into constituents of communicative units. The intonational forms of communicative unit constituents bear functions at the information structure level. The intonational analysis has a functional description component which applies functions at information structure level to constituents of communicative units at any level of the utterance tree.
