Stewie, thanks for noticing that I mentioned yodeling. I listened to the DeZurik sisters (your link) once again. I especially noticed how sweet their high notes are in the exposition.

Another thing I like to do is find and play good pieces of country music. June Apple, Midnight on the Water, Seeing Nelly Home, Sally in the Garden Assisting Sam are a few of them.

I just discovered the varsovienne and will be posting two examples today.
