music

The manipulator is a skillful pianist whose playing goes unnoticed. Your brain can be seen as a your keyboard - the brain produces ideas, the keyboard produces music. The manipulator uses it for his/her purposes ... instead of teaching you how to play it for your purposes ...

This is why if you are manipulated you will hear some music in your head which does not belong to you ... off-key moments symbolizing your discrepancies with yourself and with the world around.
