Sounds like the rowels are the part of Western Spurs that jingle. But I didn't look it up. ***


"I got spurs that jingle, jangle, jingle
As I go ridin' merrily along
And they sing, "Oh, ain't you glad you're single"
And that song ain't so very far from wrong"

(I GOT SPURS) JINGLE JANGLE JINGLE

which looks like a nice resource for song lyrics (but watch out for a lot of pop-ups and who knows what else...)

*** I take it back. The spurs look to be only the part attached to the boot by a strap and with a single spike/axle on it. The rowels are what spins on the axle (and jingles). Some are much pointier than others... see http://www.oldwestcowboystore.com/spurs/
