There are scientific studies exploring whether the history of our ancestors is somehow a part of us, inherited in unexpected ways through a vast chemical network in our cells that controls genes, switching them on and off. At the heart of the field, known as epigenetics, is the notion that genes have memory and that the lives of our grandparents — what they breathed, saw and ate — can directly affect us decades later.
If this idea turns out to be right, it would help explain families like the Bachs.
It would also further convince me that people growing up in musical households where music is a second language will never be able to appreciate what it's like to come to music making on one's own outside the home and later in life. To my mind, so much that natural musicians assume - have in their genes, know without learning - has to be approached very differently for people without that advantage.
