A Definition of Fear

If you were to be asked the question “how would you define fear?” what would you say? For me the answer would be musical.
As a boy I was taught the violin by a wonderful teacher who used the “Tune A Day” books. Despite her best efforts I only ever got as far as Book 2 and even then, not to the end of it. It occurred to me that the most frightening experience you could possibly have would be to be in a band playing a rough honky-tonk bar when the singer says “Hey lets do the Charlie Daniels Band's The Devil Went down to Georgia”. When it gets to the part where Satan shows Johnny what he can do, I would only be able to play “Twinkle, Twinkle, Twinkle Little Star”. When Johnny then plays fiddle to save his soul, do you really think Satan is going to be terrified by “Sur le Pont D’Avignon”? Do you think Johnny is going to escape an eternity in Hell? What about the audience in the Rusty Spittoon?
This I think, defines fear.
