MAIN POINT: When I was much younger, I used to place my fingers randomly on the fretboard of a guitar or haphazardly on the family piano and just hope against hope that my fingers had magically discovered a chord. Nope. Whatever terrible sound I had concocted, it was definitely not a chord, or at least not a chord that anyone musical would ever consider using in a song. I was dumbfounded. Where exactly did chords come from? I later found out exactly where chords come from, and I want to share that knowledge with you.
