There is something called the Sacred Sound Current which correlates to the spiritual Hindu "OM" and the Sufi "HU", and the Sant Mat "Shabd". This Music of the Spheres, Logos or Word as called in mystical teachings, goes beyond our limited spoken language. Such ethereal music is referred to also as the Sound of God or the Breath of God since the sound permeates all things. And as we know, all things are composed of energy.
Ethereal wave, also called ethereal darkwave, ethereal goth or simply ethereal, is a subgenre of dark wave music and is variously described as "gothic", "romantic", and "otherworldly". Developed in the early 1980s in the UK as an outgrowth of gothic rock, ethereal was mainly represented by 4AD bands such as Cocteau Twins and early guitar-driven Dead Can Dance.
