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 no longer gather together (the sumbios) in concert halls and stadiums, the places where music is performed will also be new. Composers, musicians and architects have work to do. Young people are hungry for their creations.
