Resumo

The present research intends to demonstrate the possibilities of collaborative musical formation within a musical group constituted by amateur musicians who, starting from previously absorbed knowledge, transmit the same to new members. The group in question was object of a PhD Thesis and intends to serve as a model for an extension project to be adopted at a Brazilian Federal University.The methodology used in the initial research was fundamentally based on participatory observation. This type of musical grouping, uncommon in Brazil, was identified as a tuna. About fifteen to twenty members of the group are members of the group, with three voices playing a string instrument (guitar, cavaquinho, mandolin, banjo, etc.) and percussion. The processes of teaching learning take place in two distinct moments: in ordinary rehearsals and in public performances, comprising the learning of instruments and chants through listening, observation and repetition. The basis of this type of grouping presupposes a spirit of democracy and collaboration, where knowledge is exchanged and decisions about repertoire and arrangements are taken collectively. Basedon the work of authors such as Margarete Arroyo and Regiana Wille on informal musical education, and using an ethnomusicological approach based on the thesis in question, we will seek to elucidate how these exchanges of knowledge occur, systematizing the stages of these informal procedures of teaching learning.
