Close exposure to live music, attainable, touchable, reachable, createable by mere mortals (vs the infinitude of canned “perfection” in our pocket) — this is key.
From the comments: “I wonder how many tiny people became musicians that day. All it took was hearing Beethoven on a CD in 1993 to send chills up my little spine. Years later I became a 1st chair trumpet player, then guitar player and singer eventually winning a scholarship to college for my efforts. Music unlocks the soul, and strengthens the mind. Hope you all enjoyed it as much as I.”
