In the Symbiocene, music will represent the sonic re-integration of humans with the rest of life and life forces. Such music will not be a repetition of Classical music but a new synthesis within the Harmonia Mundi where sumbiophonic music of the ecophony, the somaphony, the cosmophony and the androphony will combine and merge in creative waves of innovation. Lovers of music will gather together (the sumbios) in places where life, architecture and music meet in harmony. Composers, musicians and architects have work to do. Young people are hungry for their creations.
