It's been 10 years since my grandmother was diagnosed with Alzheimer's disease. In that time, music has become more important than ever.

Music is tied to so many memories of my 87-year-old maternal grandmother, Rosemarie Earle.
As a little girl, my mom Suzanne would put on mini concerts for the kids in her neighbourhood and perform old show tunes my grandmother had taught her. For my dad Fred, it was compulsory that he dance with my grandma at weddings and parties whenever Tony Orlando's "Knock Three Times" would play over the speakers. "Come on, Freddy," she'd say, pulling him up out of his seat.
