Walter Mantovani is an experimenter, musician and free researcher in the field of "harmonics". Since his youth he has had numerous experiences in choral singing, ranging between different genres: early music, opera, jazz, gospel and contemporary minimalism. He began practicing overtone singing in 2009 as a study and research activity and since 2012 he started teaching the technique. For more than a decade he is involved in research and experimentation in the field of "acoustic arts" with particular interest in the integration of phonic techniques with traditional ethnic instruments and modern electroacoustic instruments. In 2011 he created the site "", a divulgative portal that aims to collect information and audio/video finds on overtone singing and on the phenomenon of the "harmonic series" in particular. Since 2012 he collaborates with the musician and music therapist Alberto Ezzu as a overtone singer in the homonymous Alberto Ezzu Lux Vocal Ensemble with which he participated in the realization of two albums and numerous concerts. In 2018 he is author and editor, together with Alberto Ezzu, of the second edition of the book "Il canto degli armonici. Storia e tecniche del canto difonico" (History and techniques of overtone singing). In his working life he is a consultant and teacher in the ICT and creative industries.
