This is probably the #1 life event that comes to mind when the pipes are mentioned.  Only 'TAPS', well played, can equal the power of the pipes coming from the distance.

When and where in the service can vary.  For formal uniformed services, one or more pipers may perform a processional leading the casket into the service, and / or a recessional leading out.

It's also common to play:

• as the casket is being placed into a hearse.
• as the casket is being moved from hearse to grave
• as a flag is being folded
• as the last sound at the end of the service
• or any combination of the above.

Reference Accounts

To date I've played solo at the funerals of:

• The Fagan 5 (5 confederate soldiers discovered in a battle grave, and re-buried in the confederate cemetery in Helena, AR.
• Former Fire Chief's of Walnut Ridge, AR & Marion, AR
• Helena, AR police officer LODD
• Jonesboro, AR police officer, laid to rest near Sikeston

A few notes that insure all goes smoothly: (What time the service is.. always helps)

    At Graveside:

• Some way to give clear signals as to when to play.  Since the pipes are typically some distance from those gathered, I can't hear what is going on.  It can be a 2-way radio, specific person that will point or wave, Rifle volly, Taps, or Ringing of a bell are all usable.
• Some way to know when the procession is leaving the service, enroute to the graveside.  This insures tuning is completed prior to arrival of the mourners.
• If there is any chance of precipitation, Some sort of cover should be available.
• Clear directions to the cemetery, if it's a large cemetery - what section will the grave be in?

    At the church / funeral home

• What church / funeral home, Directions?
• Place to tune.  It can be distracting and even distressing for family and mourners to hear the less than perfect sounds which emanate when tuning.  Also, in order for the tuning to be effective and accurate for the performance, the location should be as close in temperature and humidity to where I'll be standing for the performance, as possible.  If communication is good enough (cell phone / 2-way radio) I might be able to tune in a different building or half a block away or so.
• Clear understanding and communication as to what to play, and when.  If there is an honor guard.. do they know there's going to be a piper?  Typically, the piper leads the honor guard in and out. I've played funerals with the Jonesboro PD & FD, Shelby County Sheriff, Memphis PD & FD honor guards.  Each can be slightly different in protocols.

    Payment:  It may be easier to have the funeral director make the arrangements with me, including payment.  That way communication is assured and a family member need not have this concern.  Of course, if the director is hesitant or dismissive.. (I'd be surprised).
