I can't begin to say anything very wise or helpful. Please allow me to say that I am just so sorry for your loss. I pray for you and your family, and I also pray that your mother now finds the peace and freedom that escaped her during her life. I do know that God sometimes ends the sorrow and pain for us when it is too much to bear.

"Flowers of the Forest," "Amazing Grace," and "Going Home" are good pipe numbers and appropriate for a funeral service. You have good advice above about pipers' practices, etc. Here are a couple of examples of good service music.
