This is a tough instrumental. It was written by Bill Monroe. There's a challenging cross-picking lick in the main melody. If that is something your struggling with, use Focus. Tap on the measure, that will allow you to use Focus. Then it will loop only the measure you selected. You can use the tempo slider to find a comfortable speed.
There's also a lot of great licks in the switcher. Some are options to make tough measures a little easier, and some show you cool ways to interpret the melody. Have fun with this one.
