One of the keys to having an excellent rehearsal is preparing great worship charts. I have found that worship bands frequently go into rehearsals with haphazard charts. No one has taken the time to really think through all the details of the songs. Next level leaders are prepared and a big part of that preparation is working on excellent charts.
There are two main forms of charts: a) the fully notated SAT chart, b) the words and chords only. I prefer the full written out chart because it gives you more details. But whatever charts you use, ask yourself these 7 questions to make sure the charts are clear and well-thought through.
Great advice here for helping to make your worship rehearsals smooth and efficient. Read the whole list here.
