Proparoxítonas no português arcaico: uma análise por meio da música e do texto das Cantigas de Santa Maria

This paper aims to conduct a study on proparoxytones in Medieval Portuguese through an innovative methodology based on the observation of coincidences and no-coincidences of musical and linguistic prominences of poetic texts with musical notation.. This methodology allowed us to verify the existence of a hundred and thirteen proparoxytones words in a corpus constituted by the first hundred Cantigas de Santa Maria. It was possible to locate the stressed syllable in 92,93% of the found words.
