I say Jerome you're way out, I say way out...
Scales have nothing to do with fingerpicking. What April needs is the basic clawhammer travis pick.
Just tried to find a simple lesson or video online and failed, all I'm getting are various pinch picks, arpeggios and complicated travis picks so here goes for an E chord
E----I---
B------M-
G--------
D--------
A--------
E---T--T--
Where T is thumb, I is index and M is middle finger ( I hope I got index and middle rightways round). Here's the same for an A chord.
E----I---
B------M-
G--------
D--------
A---T--T--
E--------
Notice how the thumb plays the root note of the chord which in the case of E and A is the corresponding string. Here's D;
E----I---
B------M-
G--------
D---T--T---
A-------
E--------
I'm showing the index and middle playing the outer strings but the could move inside so as to pick out more of the held strings.
If anyone can show me a link to a better lesson for this picking I'd be grateful as my diagrams suck (try pasting them into a document with a fixed width font).
This basic pick pattern will let you into a huge range of folk and country songs. There are many more pick patterns that may be better for particular songs but this is how to get started and gain speed and confidence. Keep practising it.
