Ok, I feel there needs to be some definition made about what actually makes music mystical and what is music. It has been observed that in most mystical traditions throughout the world cosnider music to be an expression of the in-effable. That which can not be conveyed through conventional language. Even ithe stories of the old testament about the angelic choirs that sung out the logo's in adoration to the primodial creative conciousness. The word was seen to be given substance and form by the relationship of sound and intent bestrowed upon it by the archetypal forces that shape the creative processes of the visible universe. A universe that could be speculated to have begun with the original base waveform. Ommmmmmmmmmmmmmmmmmmmmmmmmm
There is an early pioneer of electronic music named Karlheinz Stockhausen. He employed music as a medium to convey different phenoma in nature and felt that music that is considered to bring one closer to god, does so by conveying different elements that make up the natural world. Such as the interplay of darkness and light, the changing of seasons, the planets rotation of the sun, the suns rotation around the fixed stars. His music style is somewaht complex as the major celestiial force that inspired his music was the trinary star system of sirius. Apprently it is an astronomical observation that there are certain ancient super dense stars that the younger stars of the outer solar systems rotation is depedant upon. This evokes idea's of a relationship with the supernal triad. That all rudimentary forces are dependant upon the electro-magnetic relationship they have with the celestial forebearers.

I consider psy trance the most objectively mystical music I have encountered. Each person has resonates with particular frequencies that reflect the nature of the personal quintessence. However there is certain music that is based more upon mathematic formula's and how these formulas and frequencies affect states of conciousness. Psy trance is one such style of music that is deliberately designed to produce Alpha brain waves in the listener. I have observed that in prior to being exposed to this tyle of music, certain sensory synchoncities would need to be artifically created through ritual magick in order to shift brainwaves to the same state of mind that is automatically evoked with psy trance. Since becomming aware of the mystical properties of the music, it has become the major mystical practice that I employ. As is the same with ritual magick, the nature of the trance is ultimately dependant on where the magickal will is directed once the limits of the concious mind have been overcome.
I believe that we are at the age of abolishing that which was formally known as being mystical or magickal and are beginning to understand the mechanics involved to produce an alternation of conciousness, independant of any personal beliefs or experiences that are produced by these altered states of conciousness.
And very similar to the shaman that only required a drum for the spirits to manifest. We only require a certain environmental trigger for our minds to be able to access the most abstract and supernatural states of mind.
It's not how you get there, its recognising when you are there and getting to work.
