Two strings at once: a double stop for every chord, in first position, mostly on the G and D strings Fiddle fingerings →
Fiddle double stops · first position · G D A E
Two notes can only hint at a chord, so each box picks the pair that says the most: the keynote with the third where it can, the 7th in a seventh chord, or a bare fifth when that's the friendliest under the fingers. Shapes on the G and D strings come first, then the D and A strings when the chord sits better there.
