Interestingly the underground Chinese church uses a method called tin kay for teaching worship piano. For instance all major chords are represented as 047 And if a beginner counts their piano keys, just with those three numbers, they can now play all major chords. Add 037 and they can now play all minor chords This vastly beats memorizing each key combo for each scale This method came from asking God for a revelation on how to teach piano, and they attribute it to Him
