Voice and singing in historical and archaeological places to travel through time through sound. Sound and vocal performances through research and experimentation within spaces that have extraordinary architectures and reverberations. To have a connection with the historical, geographical and cultural depth of the origins through our "Voices of Inside" to create "Other Spaces" and improve perceptual and vocal emission qualities. With Voice and musical instruments it’s possible to improvise in total freedom, being inspired by the strong relationship with the places and using instruments that conform to environments such as percussion, wind instruments, string and string instruments, shells, stones and water. The places of the performances were: The ancient Baths of Baia, The Castel Sant 'Elmo (Naples), The Castel Maschio Angioino (Naples) In addition to the artistic, therapeutic, sound and experimental experience, the project proposes itself as a path to enhance and enjoy historical, archaeological, modern and postmodern sites and communication between old and new traditions, creating live performances and audiovisual productions. The author has been bringing the experimentation and research of The Voice in the Ancient Spaces to various Italian universities, conferences and academies for over 10 years.
