This paper aims to highlight, as a case study, the encoding of a Spanish traditional music corpus using the MEI standard for the development of an interactive traditional music database focused on preserving and disseminating this type of cultural expression in the field of music education as well as ethnomusicology research. It analyzes the possibilities of the schemas and the guidelines followed to describe cancioneros at the bibliographic level, as an archetypal form of compiling traditional music in Spain, as well as the analytical aspects that highlight paradigmatic elements of this kind of music such as rhythmic patterns, tessituras, modal contexts, phrases, structural forms, etc.
