My father was a professional musician as his main career. He also taught music at BYU and other universities. He invented several tools that are used to tune pianos. They are still being used years after his death.
Once he made several sets of very accurate chimes/ pipes with everything needed for a big family group to play Christmas hymns, including both sharps and flats. He made posters too.
After Christmas dinner, we gather around the piano and sing / hit chimes. Every age enjoys... but the kids have more fun than the older people. But we love it, and play these hymns together every Christmas.
