I found a free resource I wanted to pass along to you all today. This will be especially great for those of you who are wanting to help move your bands into the direction of learning more music theory &/or the Nashville Numbering system.
It’s called Discipline of the Groove.
He’s got a great, short explanation of why to use numbers. As well as some example song charts using numbers. He’s also got a few articles that go over Chords, Keys, Intervals & Scales.
I hope this helps you in your desire to improve worship in your church.
