I co-founded @audioalchemy with by friend @hedflux as a vehicle to explore the application of alchemy to music. It's actually been surprisingly effective. By studying alchemy and then using the law of correspondences to apply laboratory alchemy principles to music production, it has completely transformed our relationship to music.
If you're interested in learning a bit more about it, here's a post that outlines the basis of our philosophies: https://steemit.com/introduceyourself/@audioalchemy/the-alchemical-revival-in-music
Interestingly, the more we learn about alchemy, the more we discover that music played an integral role in the lives of many great philosophers and alchemists.

The moon moves the oceans and the human organism is mostly water.
It all comes down to energy, frequency, harmony and resonance :)
