This morning, while staring at a violin Christmas ornament I've had for decades, I announced to no one, "This violin has no strings." Everything else about it is an accurate replication of a violin. Then, I thought, "It's an ornament, just like this trumpet ornament and French horn ornament. None of these ornaments are meant to be played; they're meant to enhance a Christmas tree."
Besides, who says a violin ornament can't be a violin-in-progress ornament?
