Dirt simple but so effective.
Nora Jones Cold, Cold Heart. --
http://www.youtube.com/watch?v=g35zS1tVO3o Taking the old dirt simple and bring it into the jazz world. With comments on the bass guitar's choice of riff. Best I can tell it's the major pentatonic over the entire song - welcome comments on base line , not a construction.
It's a double bass, of course, not a bass guitar! 
It's essentially using the root 5th and 7th of each chord, with a passing 4th. Here what it would be for bass guitar:
Code:
G----------0-------------|-------
D----------------0--2----|----------
A-0----------------------|0--------
E------------------------|--------
1 . 2 . 3 . 4 . 1 etc
This is partly what makes her version jazzier/bluesier than Hank's original: the bass is adding the b7 of the tonic chord. (The other thing that makes it jazzier, of course, is Jones' own piano playing: very free, not really country at all.)
Theoretically, this is an example of beautifully simple popular songwriting: the kind of thing country was always good at, of course (combining folk, blues and popular song forms, before rock'n'roll), but Hank was a master - no, THE master. No frills, nothing superfluous. 3 chords and simple, memorable melodies.
Here's an analysis (for what it's worth!):
|I - - - |I - - - |I - - - |V - - - |
|V - - - |V - - - |V - - - |I - - - |
|I - - - |I - - - |I - - - |IV - - - |
|V - - - |V - - - |V - - - |I - - - |
That's the basic format, but Hank (in key of D) extends the 3rd line - 1 more bar on the IV chord to stretch that high vocal note. (I love the little smile as he sings that note, and stretches himself slowly to full height each time - obviously the bit of the song he really enjoys, the peak of intensity.) And from there the melody descends gracefully to the tonic.
In contrast Norah Jones (key of A) dispenses with that extra bar entirely (keeps the 3rd line to 4 bars), but adds a bar to the first line. So the pitch of intensity at the end of the 3rd line is diminished, while the effect of extending the 1st line - without a corresponding held vocal note - is kind of coolly marking time, as if considering her options, or just enjoying the groove for a moment longer. It puts a little more emphasis on the I-V chord change too, as if the 3rd bar of the vocal was the extra bar, and the V chord is starting again. She also adds a few more bars between verses, just keeping that gentle groove flowing.
More simply, these little variations stop it from being too "four-square", too predictable. (It would be possible, in performance, to extend any of the lines by an extra bar, or all of them.)
The other thing that helps it move, harmonically, is adding a 7th to the V before returning to I, and to I before moving to IV. (In Jones's version, the 7ths are there all the time in the bass anyway.)
Both versions - very different in themselves - are a masterclass in feel, in holding a cool groove. (The studio version of Hank's original was somewhat faster than this deliciously relaxed tempo. He was in the habit of taking heartbreak songs at unsuitably jaunty tempos, IMO. Not on this video tho.)
The melody is mostly scale-wise descents, but incorporating chromatics here and there. Eg the melody of the 2nd line runs like this (written in chord tones):
Code:
|V | | |I
|3-2-2-1|1-#7-b7--|3-7-6-#5-|3
The #5 on the V ascends a half-step to the 3 of I. This is a typical blues-country sound. The melody could simply have descended to the P5 before going up again, but that flattened blue 3rd (#5 of V) adds a crucial melancholic element.
