The new MEMOSOLF methodology presented in this book is in correspondence with the transformations that the society of the 21st century demands from music education and in particular from the teaching of Solfeggio. It is inserted in the framework of a socio-cultural constructivist paradigm and is based on learning activities (tasks, theoretical exercises, tuning patterns, rhythmic reading, intonation, dictations, contests and others) to teach and learn in a meaningful and creative way, exercising the musical and emotional memory of teachers and students in Solfeggio classes.
