A friend of mine gave me this 65 page booklet from 1926 that she discovered in her attic. I started looking at the beginning pages and saw the “18 most used chords”. The first chord was labeled “D” which was diagrammed as placing the ring finger on the 3rd fret of the A string. HUH? Isn’t that a “C”?
Check out my attached – it’s the cover page and a practice page with lots of chords……but they are all wrong. Have chords changed in the last 100 years and do I need to toss this book?
