Around my parish (back when there was a lay LD):
- Plan weddings, funerals, other special events. Meet with people involved in those.
- Do all scheduling, whether they are for special events mentioned above, or the normal activities. This included EMHCs, servers, ushers, lectors, and any other volunteers not related to music.
- Train said servers, EMHCs, lectors, and so on.
- Do the Mass intentions
- Keep the church stocked with everything necessary for Mass: candles, hosts, etc.
- Oversee the sacristans and any workers involved in working inside the church (again, excluding musicians)
- Coordinating plans for liturgies so everyone is on the same page. Included working WITH the music director (but not doing his job)
The music director handled:
- Playing the organ
- Working with the choir/cantors, traning, practices, recruitment
- Arranging music for the Masses, scheduling cantors/choir
- Scheduling any substitutes
- Maintenance of the organ and other musical equipment
- Purchasing/gathering of new instruments and music
- Any research involving music and appropriateness to the liturgy
- Working with those involved in weddings, funerals, etc., for planning music, special rehearsals, etc.
- Helping the priests with any chants that needed to be sung
I’m sure none of those are complete lists, but it’s off the top of my head. If your LD does everything in both lists, then you have a 2-in-1. I think most churches would most likely refer to them as a “Director of Worship”.
Now, everything in the first list is pretty much pulled from other people’s jobs in order to create a new job. A lot of the first is either the pastor’s or secretary’s work. In my experience, a Liturgy Director is an unnecessary cog in the wheel who does more to get in the way than help. He is just another person to have to pass information through instead of working directly with the pastor, and it actually makes for a less-than-desirable work environment. He does not do anything that another person cannot do in their ordinary job. On the other hand, a musician does a lot of things that others cannot do.
