That sounds like a quite lovely creation story; although, I fear, you have lost me somewhere within the terminology.
Words have always held power from the first that the Creator spoke to separated light from darkness and the world and all things into existence. Music is a powerful extension of that and the soul’s ability to express sorrow to jubilation to exaltation. It is a universal cord that binds all life.
However, if music was our soul, I would be very much in trouble as I cannot carry a tune to save my life.
