I know that jazz musicians and fancy pickers can use more frequent chord changes and fancier chords, but I find that this chord sequence works just fine for me:


I'm Looking Over a Four Leaf Clover
Words & Music by Mort Dixon & Harry Woods, 1927
Recorded by Art Mooney, 1948

               
I'(G)m↓looking o(Em)ver a fo(G)ur-↓leaf cl(Em)over
                           
That (A)I overlo(A7)oked before;
                     
O(D)ne leaf is su(D7)nshine, the se(E7)cond is rain,
         
Thi(A)rd is the ro(A7ses    that blo(D)om in the la(D7)ne.
      
N(G)o ne↓ed expla(Em)ining, the o(G)ne re↓mai(Em)ning

Is so(A)mebody (A7)I aE7do(A7)re.
         
I'(C)m looking o(Am7)ver   a fo(G)ur-le(Bm)af cl(E7)over

First Time:

That (Am7)I o(A7)verlo(D)oked b(D7)efo(G)re.


Last Time:
That (C)I o(A7)verlo(D)oked b(D7)efo(G)re.

I do modulate the finger positions for some chords like A7 (e.g., different fingerings for the same basic chord) but I don't know how to designate those changes without drawing diagrams.   I just find that, e.g., if I stay on A7 for a measure or two, it makes it more interesting to change from the 0-0-2-0-2-0 position to either 0-0-2-0-2-3 or 0-0-2-2-2-3 at times. Not essential but makes the chording more interesting to me.

(In case the "walk-down" arrow doesn't show up right on some people's browsers/computers, if you see something funny-looking between the G and Em, it's supposed to be an arrow pointing downward.)
