The aim of this paper is to analyze some of the methodological contributions chosen by me for describing some guiding principles for a didactics dedicated to the music ensemble class and to demonstrate how the two fundamental topics examined, the reticular didactic and the simplexity, although developed in parallel, without any contact points until to a very recent experience in 2017, can be integrated and probably also complementary, as in a worthy association between theory and practice. A final nod with a conclusive intent is that done on the declination of the concept of sociomotricity in the musical field.
