Piano duets are a fun way to include other pianists from your congregation and add something special to your worship services. Plus, they’re just fun in general, am I right?
In my experience, even small churches have at least one person in the congregation who has some playing experience. Often, they just need to be asked and invited to participate.
Reach out to a few people in your choir or congregation who you know play the piano and ask if they’d be interested in playing a duet with you in worship sometime. If so, choose a collection (I recommend purchasing two copies so you can each have one to practice with).
Find a time when you can get together to practice.
If the person you’re playing with is fairly accomplished and feels comfortable sight-reading, spend some time reading through some of the pieces to get a feel for what they sound like with both parts. If that’s not realistic, choose a few pieces to begin working on, decide who will play what part, and set up a few rehearsals in the coming weeks.
