I've looked at a few different method books and they don't seem to agree on which scale or key to learn first. I have a good grounding in theory (piano too many years ago) so reading in the key of Cmaj or E#min or anything between is a non issue for me.
BUT...
Doors - Riders on the Storm: Manzarek composed a bass line on the keyboard so easy my cat could play it, but Scheff had to go through "machinations" to play it on the bass.
So my question is, are any scales or key signatures physically harder to play on the bass or is this story more related to the shift between Emin and Amaj chords? Is there any rough consensus ranking scales from easiest to most difficult?
