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
|Em |Am |6 |2 |1 |4 Left my fear by the side of the road |C |D |4 |5 |6 |7 Hear You speak You won’t let go
What is the better way to number it to learn this song better long term?
