During a conversation I had with an All-State High School Orchestra musician in 1987, this violinist who also played guitar mused, "One of the mysteries God gave us when he made this place was..."
...Any guesses as to how he completed that statement? Did he elaborate upon the inclination humans have to be compassionate even when it isn't reciprocated? Did he mention the instinctive nature humans and animals have to do things they haven't been taught? Did he surmise that some of the things we think are coincidences aren't coincidences, after all?
No. Instead, he continued,"...when you press your foot on a pedal while playing guitar, you get the word, 'Wah.'"
And, so you do. While it might not be the loftiest mystery God left us, it's mysterious, nevertheless.
