John Bayley (circa 1847 – 1910) was an English bandmaster, clarinetist, violinist, and organist who was active in his native country and North America.
Cornetist Herbert L. Clarke described him in his autobiography as "a finished musician of high order; he was a remarkable organist... and one of the best clarinetists I have ever heard in my life.
The family moved to San Francisco in 1857 and then a year later left there for Victoria, British Columbia in the enthusiasm of the Fraser Canyon Gold Rush.
In 1861 the family returned to England, partly to provide Bayley Jr with superior music teachers than could be found in the United States.
He entered the London Academy of Music where Leopold Jansa was his violin instructor and Henry Wylde taught him harmony.
