Do We Have This One?

Want to underline just how feminine and ladylike a woman is? Make her play the harp.
Just like playing the electric guitar is often a sign of absolute manhood, the harp's crystalline and delicate tones as well as its graceful shape will exacerbate the femininity of the woman playing it. As such, harp playing women in fiction are almost always important to the plot in some way.
At a lesser extent, the lyre can also have the same function but it's less common.
This is also Truth in Television
since harpists are mostly female.
