Music played or performed should be a tribute to the deceased. Music provides quiet background. Consider a playlist of favorite songs of the deceased, playing while guests find their seats, and at the conclusion of the service as people leave.
Often in a memorial service one or two songs are played during the service. Some people select hymns. If possible, let the audience know that the song selected was important to the deceased and explain why.
A favorite song of the deceased can be played in the background of the funeral video tribute of your beloved’s life.
Perhaps live jazz or bluegrass was a favorite in which a local band could be obtained.
Another option is to perform a favorite song by a soloist.
