Guía didáctica para el aprendizaje del acordeón diatónico de tres hileras de botones a través de canciones infantiles

The objective of the research was to propose the learning of the diatonic accordion through nursery rhymes in fourth-grade children of the Annex No. 3 of the Rafael Valle Meza school in Valledupar, Cesar. It was located in the qualitative paradigm, with a Pedagogical Action Research methodology which was developed in three phases: deconstruction, construction and reconstruction of the practice. The work unit consisted of twelve students of fourth grade. The results indicated that the use of the didactic guide facilitated them to learn the cognitive aspects of the accordion, such as reading the musical language, acquiring cognitive competencies, and developing auditory perception. It was concluded that the implementation of the didactic guide allowed them to learn the diatonic accordion in a systematic and organized way, maintaining the correct posture, so that the music flows more easily.
