Your words and music

This is optional. It exists for the living, not the dead.

Words

You can leave guidance for a eulogy, or leave nothing. Both are valid.

Music

Music can hold memory. It can also be unnecessary. Both are valid.

You do not need bespoke music. You do not need to spend money. You do not need to perform.

Practical tip

If you want something specific, write it down in one place and tell one person where it is.
