The Mixtur Festival opens its doors to Primary students and teachers to get closer to new music. On this occasion, the Sidera saxophone quartet will show us how the work Knossos by Alberto Posadas works, which it will perform later in concert. We will be able to see how the quartet studies various passages and highlights their sonorous and expressive qualities. The children attending will be able to ask him questions and share his opinions and feelings with them. The session has been prepared in the classroom with the teachers of each group, based on the analysis of the play (adapted for children) and attentive listening and comments.
