I sped level a bard and notice there's a "fiddle" performance skill. Well being from the land of Bluegrass and Dixie I got excited, until I heard it. That's no fiddle, that's an electric viola. Below is a few suggestions on how to make the fiddle sound a bit more distinct than "harp number 5".
1. Make is raspier.
2. I will send Yoshi-P genuine country boy goodins.
3. Hire Charlie Daniels.
