How do you time the worship lyrics? This is a question that I have often pondered as I was running the presentation software. If you change the slide too quickly, then people may get lost. If you change it too late, people will feel confused if they don’t know the song. The timing needs to be close to the mark. But how do you determine where the mark is?

I’d like to find a good psychological study of this question. It would need to address the reading speed of the congregation, since that is a factor. It would also need to address the pacing of the music, since that is also a factor. Would it be possible to come up with a precise rule for timing the slides? What do you think? I have often used the last line or even the last word as the point where I press the down arrow to move forward. And the software has a response time, which is measurable. For that matter, the video projection system has a response time. There ought to be some way to factor all of this together.
