I would be nice if It could rotate the body of the piano by Graphical user Interface and see what sounds sound at the angle towards the camera.
It is an image of watching the piano from the microphone.
or Audience position
I think that it is good as an approach, regardless of the location of the microphone and the size of the environment, but the setting of where to listen to the piano from.
It is on the extension line of act of listening while playing on its own.
Thanks.
