This is a really cool item as it gives you and others so much enjoyment. I'm a musician also, piano and trumpet of all things, but I haven't played the latter for a little while. I understand what the instrument comes to mean.
I'm sorry about your dad, I lost mine last year so understand. Mum left quite tragically several years ago too...I miss them both. They're in our memories though.
What instruments do your children play and do they sing?
