Music does something readings and eulogies can't quite manage — it changes the temperature of a room in seconds. A well-chosen piece can turn grief into something gentler, or turn a solemn moment into one people can smile through.
Some families choose a single song and let it carry the whole service — played once, deliberately, at the moment guests walk in or the moment they walk out.
