This book is the result of an international conference that took place in Rome on September 13th-14th 2019, entitled “Resounding Spaces: Music and Atmospheres”. The main topic was the relationship between music(s) and concepts like resonance, atmosphere, and mood. Talking about “music(s)” and not “music” (in singular) is a necessity because of the academic backgrounds of the authors: philosophers, musicologists, ethnomusicologists, aestheticians of music, composers, etc. have given their particular contribution, within their own discipline, enriching the volume with very different points of view.
