I learned most of my songs in the Major key and used a number system to learn it to be able to transpose the song easily. I now have a minor song I am learning and originally used the Major numbers to learn it.
ie for this song in Em I named the Em chord 6 (as in realtion to the Major scale, opposed to 1 for its minor key) and so on for all the other chords. This has the advantage that I know 6 is a minor chord in relation to a major root. However I have been told its better to number the scale from the minor root, in this case Em = 1. However I find that I don't get used to thinking in this way (I often think 1 is Major), are there any techniques to make it easier?
Eg for this song (Em scale) I can write it in these 2 ways
Left my fear by the side of the road
Hear You speak You won’t let go
What is the better way to number it to learn this song better long term?
