I placed Bose headphones on my belly when pregnant with my daughter. She ended up playing in the Kennedy Center Youth Orchestra and got a college scholarship in music performance.
My mom was a piano teacher. After I was born she said I would scrunch up my face when a student made a clinker. I was playing 2 hands, harmonizing, before I could walk or talk. My siblings also are musical. Babies do hear through the thin skin covering the womb area.
I’ve heard mothers are teaching languages before babies are born.
It’s all very cool. So many possibilities.
