The aim of this communication is to present the state of the research related to Basque prosody. On the one hand, after having defined the boundary of our reference field, the state of current researches will be presented. On the other hand, the focus will be put on some methodological issues that have been raised by experience grounded researches. This last question is directly related to change and evolution. These research works will be a part of an integrative project incorporating the whole Basque Country. The following aspects will be considered : prosody's fields, prosody's linguistic aspects (stress and intonation), paralinguistic aspects (attitudes), non-linguistic aspects (age, sex, physical state, emotions) and the characteristics of the fields of investigation that must be taken into consideration with today's Basque people (geographical, social, stylistic).
