Not your everyday word--skirl--but it's one that can bring descriptive precision when you need it.
1.) Though bagpipe music may not be a part of your quotidian experience, you can, on those occasions when you do hear a bagpipe (such as parades), be ready with the most prescriptively accurate word we have to describe the instrument's unique sound: the skirl. "Hark! I can hear skirls and drum beats coming from past the curve in the road. The parade's about to arrive!"
2.) Using skirl to identify sounds similar to those of a bagpipe can bring onomatopoetic resonance to a phrase or sentence, as in
"crooked old wheels skirling";
"the skirl of a police whistle";
"the skirl of the attic door opening, slowly";
"the skirl of fat sizzling in a pan";
"the skirl of fish frying in the pan."
In fact, Webster 2 lists "skirl in the pan" as its own entry.
3.) Finally, skirl can bring its unique combination of sound and movement to a scene that is primarily visual. Compare: "A whirling of snow" to "A skirling of snow."
