Each utterance is considered to have propositional, interpersonal, and discourse function, and the model shows how each of these determine a relation between the underlying syntax and semantics, and t h e surface fundamental frequency. The underlying performative and proposition control the basic contour shape, which is then perturbed by markers of the speaker's attitude toward the pro- poeition and the choice of focus-shifting transformations. The interpersonal function is supplied by modal operators which indicate the speaker's attachment t o the truth-value ~f the proposition, and we show how rnodals and t h e i r scope are realized in the fundamental frequency contour The use of focus-shifting transformations to achieve discourse effects i s also strongly marked by pitch movements, and these are characterized f o r a wide range of transformations. All of these effects are shown t o be essential f o r a comprehensive model of pitch contours.
