One time at the Master Unit in Taiwan, in dream, I saw one man playing music with a stick.

There was no instrument, there was only his stick with which he created musical waves. As he melodiously and gently waved his stick up and down, a light wave seemed to emanate from it. Its light was very soft, yet at the same time shiny. It wasn’t as thin as that of a laser beam, rather it was as thick as was the stick. Out from that light wave or from the stick came the sound of sitar music in classical Indian style. 

Maybe in the future people will appreciate musicians simply by the way these are able to express their thought waves, even if simply by means of a simple stick.
