A eulogy for musician should stress the part music has played in his or her life. Our eulogies from a friend or relative express his or her sorrow for the loss of someone to whom music was a way of life.
There are eulogies for a natural death and specific ones for a sudden/ unexpected death or for a death after a long illness. They speak of the joy music has brought into the life of the deceased and into the lives of those close to him/her.
They end with a wish for peace and perhaps music in the afterlife.
