About the app
Think in numbers. Play in any key.
Nashville Trainer is a free iPhone app that teaches the Nashville Number System the way worship and session charts are written. It drills you until you can see a number and play the chord in any key, trains your ear to hear the numbers, and holds your whole set list as number charts.
