As humanity around the globe enters the third decade of the 21st century, immense technological change is more profound than any previous time with pursuant massive social change. Central to this change is the Fourth Industrial Revolution (Industry 4.0). Three revolutions have gone before: mechanisation, mass production, and simple digitisation/automation. The fourth revolution builds on the third and is characterised by a combination of technologies where the boundaries between the physical, digital, and biological spheres are now blurred. Drawing on musical examples from Australia, this article is sited in and makes links with relevant elements of the fourth industrial revolution illustrating how music (in combination with other artforms) has enormous potential to benefit the well-being of the nation's citizens, creating unity between community and humanity. In this article (an expansion on Watson & Forrest, 2020) we focus on music initiatives that operate within Australian hospitals, the community and schools, involving marginalised members of society, with outcomes that are not specifically music-related. A variety of partner organisations and volunteers provide professional services and financial support to allow these activities to achieve their goals and remain viable. The organisations and programs under consideration are the "Hush Foundation," the "Choir of Hard Knocks," three "El Sistema" inspired programs ("The Pizzicato Effect, Crashendo!" and "Crescendo"), the "Boite Schools Chorus and Millennium Chorus" and "Don't Stop the Music." Musicians (as professionals, undergraduates, amateurs) and music educators, are involved in these types of projects either as an aspect of their career and earning a living or as a voluntary community member. Although music is a central point for achievement, the major outcomes are not necessarily going to be musical, either by design or through lack of planning. It is acknowledged that music has a significant role in the community for therapy, for healing, for well-being, and to support other academic goals.
