This study offers a phonetic description and phonological analysis of a variety of melodic contours in Brazilian Portuguese. These are commonly referred to as conveying the modal, or illocutionary, functions of intonation, as well as some attitudinal uses. The phonological analysis follows the AM framework and aims at distinguishing what is contrastive and what are merely allophonic variations of a given melodic pattern with the help of a resynthesis technique, in order to propose a more consistent (phonological) representation of the contours examined.
