After the funeral, its time for a procession:
148. At the conclusion of the funeral liturgy, the procession is formed and the body is accompanied to the place of committal. This final procession of the funeral rite mirrors the journey of human life as a pilgrimage to God’s kingdom of peace and light, the new and eternal Jerusalem.
149. Especially when accompanied with music and singing, the procession can help to reinforce the bond of communion between the participants. Whenever possible, psalms or songs may accompany the entire procession from the church to the place of committal. In situations where a solemn procession on foot from the church to the place of committal is not possible, an antiphon or song may be sung as the body is being taken to the entrance of the church. Psalms, hymns, or liturgical songs may also be sung by the participants as they gather at the place of committal.
Practically everywhere in the OCF the preference for congregational singing is stated. And the repertoire includes not only anitphons, but psalms, hymns, and songs.
I can recall ever visiting only one parish (for an interview) that had a cemetery on church property. The pastor loved having the proximity–church bells often accompanied congregational song on the way to the graveside, he said. Nice.
