Here is the Air Guitar World Champion 2007, Ochi “Dainoji” Yosuke (Japan) performing at Air Guitar World Championships 2007, Oulu, Finland:
What a nice gesture performance: the pantomime, the gestures, the emotional expressions, the mimicry of the actual guitar play, and of course the dramatic gestures of a lead guitar player on stage. It makes me realize that a language may be found around in every hidden corner of human activity. In this case Dainoji shows a hilarious command of the body language of lead guitars.
It also makes me wonder what exactly would remain of ‘musical gestures‘, when all of a musicians ‘body language’ were hidden to the audience? I guess something would remain, and that would then be the real musical gesture.
