Cacophony

Trumpet here,
  another there.
Shall we stay,
  do we fit, noise, no.
Off they fly,
  two alone, and their
Mark is left
  behind as the others
Identify, sound off,
  make sure its the core.
Finally, silence
  descends in soft trills.
Then a murmur of
  sound, just to be sure.
We are here, we belong
  just be still and it will come.
