How to coordinate a choir

I had a surprise today. Some members of the choir asked me to delegate some of what I do to them. They were all concerned that I was finding it too much (I was like what gave it away - My fatigue? My complete lack of joy? And it took you this long to notice?!). So I said I'd write a list of all the different thing I do and we could work out what others could do and what I have to do. This is it:

• Find out feasts/readings for Masses in advance (anywhere from 4 weeks to 4 months)
• Nag the PP to plan/make decisions (Seriously! If I don't, we get given really challenging music like 5 minutes before the Mass. This is a campaign in itself. I began asking for a planning session for the Easter liturgies in January (3.5 months in advance). We got around to planning at the beginning of April - 3 weeks before Easter - just too late to properly learn new music).
• Read (and read around) the readings
• Identify themes
• Select relevant songs/hymns (sourcing music if necessary)
• Narrow music selection based on what we know and how much time we have
• Pray

For each weekly practice;

• Pray
• Plan music to rehearse based on events of the next two weeks (longer if there is a big event coming up)
• Learn/refresh knowledge of music
• Try to plan a warm-up/vocal exercise in the rehearsal in such a way that no one will notice it
• Pray
• Have a good lunch
• Leave work on time
• Run rehearsal (90 mins)
• Neither say or think anything that could possibly be interpreted as a critism (including things like, 'we went flat' or 'could we sing this more quietly')
• Keep positive the whole time and take nothing personally
• Have a prepared explaination or rationale for every hymn choice, action and suggestion I make
• Remember to remind everyone of the next and upcoming events
• Leave last
• Sleep

For each and every event/performance;

• Get a good nights sleep
• Pray
• Formalise and type up music schedule for the event
• Get to Church about 30-60 mins before event
• Get music selection approved by both the PP and celebrant
• Find out what unusual thing is happening and how it will impact the music
• Put up hymn numbers
• Copy and cut music schedule for choir and celebrant
• Run performance
• Be positive and take nothing personally
• Remind everyone of next and upcoming events
• Go home and sleep

My criteria for a successful event;

1. Nothing unusual happens
2. The choir sings in tune
3. I am still standing and have not had anyone tell me off

I think I may have to edit this list slightly before I present it to everyone.
