KOSMOS accordion LAB (Eng) offers a pedagogical workshop course, articulated in work plans that are useful to the teacher in guiding the first stages of instrumental training, in both group and individual lessons. Sound research, creation, improvisation and ensemble activities lead to the immediate acquisition of technical and musical fundamentals. It can be used with all types of instruments, at all ages and at different complexity levels and stands as a guide useful independently of other materials. At the same time, KOSMOS accordion Lab can precede and integrate in parallel the process designed by all books in the KOSMOS series. The book also contains a special guide for workshops in outreach and dissemination settings.
