Do you know what determines whether a guitarist plays right or left handed and why?
It's counterintuitive. One is meant to fret with one's non-dominant hand and pick with the dominant hand.
In modern music, this makes no sense. The pick hand just does repetitive up and down movements, just like masturbation. It is the fretting hand that requires more coordination and dexterity. Modern music would be better if right- handed players were trained to fret with their right hands; they'd get better faster.
The reason is born of the mists of antiquity. In tha 19th century, no guitarist employed a plectrum, but played fingerstyle, even as classical guitarists play today. In classical guitar, more coordination us required in the picking hand, hence teachers teaching guitarists to pick with their dominant hand. Unfortunately, since 1950, classical-style guitarists are in the minority.
What useless bits of trivia do you know about?
As an added note, such trivia *can* be useful. I've got a bunch of free beers on bets about trout I learned. watching QI. QI is not broadcast in Canada.
