For all ushering service hours, plan to arrive 30-40 minutes before the concert start time.  Dress is concert attire (ladies-long skirt/dress or dress pants with dressy top in adherence to school dress code, men-collared shirt, tie, dress pants) 

     Prop the doors open 30 minutes before the concert starts.  Hand out programs as the audience enters.  Close the doors when the concert begins.  Stay by the doors to deter audience members from entering/leaving during a piece.  Direct audience members to the restroom, etc.

     When contacting a music teacher about the possibility of getting service hours at their concert, address them with proper title, use mature language (no texting lingo), and write a polite email, remembering that you are them to help them!
