Thank you very much for your reply Christopher!

I do feel like I have a reasonable grasp and intuition of scale patterns so it's encouraging to hear I should just get started with Blues 1. It feels like that is where the musicality will come more into things as opposed to 'just' the major and minor scale (though I do appreciate they are the basis for pretty much everything).

I'll definitely check out the links you provided - it's good to have some direction as it can be quite overwhelming to know where to turn when you sort of have the skills but want to focus on the theory.
