I don’t know if this is still the case, but it was once believed that the fiddle was the devil’s tool.

Well it’s mostly for show.

She doesn’t need that golden fiddle. I would weigh hundreds of pounds and sound crummy!

I’m assuming she’s gonna win and get that golden fiddle

The devil went down to Equestria, he was lookin’ for a soul to steal  
He was in a bind ‘cause he was way behind  
And he was willing to make a deal  
When he came across this young mare  
Sawing on a fiddle and playing it hot  
And the devil jumped up on a hickory stump  
And said, “filly, let me tell you what I guess you didn’t know it but I’m a fiddle player too  
And if you’d care to take a dare I’ll make a bet with you”  
“Now you play pretty good fiddle pony, but give the devil his due  
I bet a fiddle of gold against your soul I think I’m better than you”  
The mare said, “my name’s Fiddlesticks  
And it might be a sin but I’ll take your bet and you’re gonna regret  
I’m the best that’s ever been”  
Fiddle you resin up your bow and play your fiddle hard  
‘Cause hell’s broke loose in ‘questria and the devil deals the cards  
And if you win, you get this shiny fiddle made of gold  
But if you lose, the devil gets your soul  
The devil opened up his case and he said, “I’ll start this show”  
And fire flew from his fingertips as he rosined up his bow  
He dragged the bow across the strings and it made an evil hiss  
The band of demons joined in and it sounded something like this  
When the devil finished Fiddlesticks said “well you’re pretty good, old son  
But sit down in that chair right there and let me show you how it’s done”  
Fire on the mountain, run colts run  
The devil’s in the house of the rising sun  
Chicken in the bread pan pickin’ out dough  
Granny does your dog bite, no colt no  
The devil bowed his head ‘cause he knew that he’d been beat  
And he laid that golden fiddle on the ground at Fiddle’s feet  
Sticks said, “Devil, just come on back if you ever want to try again  
I told you once, you son of a peeve I’m the best that’s ever been”  
She played, fire on the mountain, run colts run  
The devil’s in the house of the rising sun  
Chicken in the bread pan pickin’ out dough  
Granny does your dog bite, no colt no
