Shall we?

Heart pumps the rhythm into the body, lungs are filled with inhaled music, the spine is playable keyboard with some strings in the place of spinal cord (connection to your mind-head), and in the front is also a moment when the last two body parts are ready to connect and release the music into the body.

so Shall we?

EDIT: Repaired some invisible mistakes annoying my eyes like
>recentered the front side - it was set a little more to right creating empty space on left
>adjusted screws on two of the speakers - were accidentally set off when I was working on it.
