My fingers glide gently across the strings, fretting each with note with an air of delicacy. Like a spider’s legs, they move, almost hypnotizingly, across the polished neck of the guitar. One, three, three, two, one, one. F major. These numbers resonate in my head as my fingers hastily assemble the chord, one-by-one. My right hand runs, almost by itself, across the six strings at cadence. Up, down, up, down. Skip this stroke, strum on the next one. The sound is low, firm, yet powerful and inspiring. Zero, three, two, zero, one, zero. C major. Happy, reassuring, bright, and warm. Zero, zero, zero, two, three, one. D minor. Skip the 5th and 6th strings; focus on the first four. Doubt, anxiety, worry, uncertainty. Zero, one, three, three, three, one. B flat. Back to normal. Stay the course, don’t give up. Everything will be okay.
