But a Satanic Jimmy Page in Crowley's digs seems pretty "In your face"...
I never knew anything about A440 untilI had been playing the guitar for 20 years!
I only played alone and would simply restring and turn the machine heads until E sounded "about right" and then tuned accordingly. I don't think that I ever even considered that each note had a defined vibratory rate. Technology and the Internet, along with a late in life interest in finally understanding music has brought a whole new world of fun as I can now "play with others" and play along with recordings.
Wha? .....hey....who stole my country?
