Find a way to provide some consistency to your weekly ministry, which gives those that want to get involved something to count on. For me – the same guy sits at the piano every week. And whether some would think that’s a good thing, or a bad thing – it provides vocalists and instrumentalists a consistent musical presence each week -which allows for various drummers, guitarists, bassist, and vocalists to rotate through and learn what to listen for when matching up strumming, beating, and singing.
The downside? It’s difficult for a pianist to get involved unless they want to play synth.
If you’re not a piano player – you can still provide consistency by being a steady guitarist, or a strong vocal that allows your volunteers something they can count on to be there . . .
