This text addresses the funeral corner of Javaé women as a musical gênery emerging from performing contexts. Killers and chores, known as yburu, are carried out by women during periods of fighting. The relationship between those corners and the myocosmological narrative will be analysed initially and then the categories of native music theory obtained by means of field research highlighting the aspects of those corners such as improvised compositions, voice music and musical narratives embedded in a performance process synthesising gênery, nostalgia, sauce and pain identities.
