A good ear for music. From the grandparents down to the great-grandchildren. It runs in the family, as they say. Even without a guide, they can play a song by ear. One round of listening to it and they can play it in the piano, guitar, and even the violin.
Every Sunday morning, the family members who now live far from the ancestral home and with their families would go back for brunch and early dinner. The engl amps, keyboards, and the instruments are in place, ready for those who would want to play. And play they do!
You can expect an all-out jamming session whenever the family is together.
