To deepen the relation between electroacoustic music and happiness, it will be meaningful to explore the possibilities of Live Electronics as a once-in-a-lifetime experience that metamorphoses the mind and body into the best. Our minds, even our ways of life are changed by others��� words and this amazing agent of transformation is transmitted to others by vocalizing and is received as dynamic force through their bodies and souls. I believe that this enchanted sonic power can be further developed with electroacoustic music and that Live Electronics will be able to realize the profound ���here and now��� experience of self-reform. AI- generated music and artificial voice will progress at an accelerated pace, and in such a period, it will be significant for future humankind to pursue the music with ���the one and only voice in the world��� that is absolutely rooted in and produced from one's irreplaceable own body. Therefore, it is vital to create spatial music that can ���enchant ourselves by chanting��� with our own voices, aiming at the mind-body transforming experience ���Voice Metamorphosis��� in which vocalization unifies body, mind, sound and space. This sort of electroacoustic music could also re-harmonize human voice with great nature sound, like Pygmy���s polyphony music harmonized with forest sounds. In future, electronic music may play a role in bringing people back to the healthy and harmonious mind/body/sound world, giving us the power to live.
