There are many definitions to 'conjuration' but this is my definition and when I use that word, I am using in this way: a person who performs conjuration is a conjurer. A conjurer expresses commands and directs requests into the base elements. That request is a fertile seed bares fruit. The main vehicle for conjuring is thought -- or should I say it is visualization through concentrated thought. But not just thought.
Conjuring can be enhanced with sound. However, strong visualization guides the power generated with sound. For example, the power of sound can be seen at live concerts -- the conjurers are the musicians on the stage.
A master musician can control the entire audience with his music -- he can make the audience sway, sit, stand, cheer, roar, go quiet, and he could do many other things if only the master musician knew it. Paul McCartney knew it. Paul McCartney conjured love and compassion and much more -- all for the betterment of life.
