Most of the congregation will not notice, but FLOW is crucial in worship planning.
Spend time really thinking about your transitions as you plan.
What key are you leaving and going to?
What are common words in the songs that connect?
What is the style of the song?
What are some common themes in the songs that connect?
When will you say something between songs?
Why do you say something between songs?
Are you using scripture on the screens and if so, how do they help the flow?
If you begin working on better flow, spend time afterwards evaluating.
Remember, it is not about the songs or the flow, but about pointing those who are worshiping to the throne!
