Tapping

Music has to be made.  Even if it's just in the sound of machinery's rhythmic tune, nothing can stop it.  It's magic.

Rhythm.  Energy transmitted.  Drilling and tapping a metal perfect fifth.

Cacophony of head-banging life.  All the players join in.  Bring the noise to a climax.  

Listen.  Everything works together like clockwork.  Knife-slicing pops of metronome heart-beat staccato.  

Now, it all makes sense.  Inside the apparent chaos is a theme.  Take a second and just listen.
