One of my favourite bits of the Symphony experience is when performers are quietly warming up, just before a conductor will march in to shut them up. A delightful sonic tapestry of open strings bowing wide resonate ratios while brief motifs might dance above freely, afforded by a last chance practice before the first beat is directed.
This wild murmuration of random sonic textures, nevertheless dance upon an underlying collective of yearning and instinctive curiousity for novel musical invention: discoveries of pattern, harmonic procession, and temporal congruity.  
So if luck would have it that your conductor is late to his cue, you might even find yourself lifted by a rogue tidal force of unexplainable magic.
