he sets my curiosity

“A rhythmic, repetitive neural oscillator”

ablaze in wonder

“sends messages to the laryngeal muscles,
causing them to twitch”

at how gentle rapidity of noises

“at the rate of 25 to 150 vibrations per second (Hz).”

makes me content, and yet

“This causes a sudden separation of the vocal cords,“

aggravated, of this sudden disturbance

“during both inhalation and exhalation -”

and yet, overjoyed at the concert

“the unique feline vibrato.”
