This great Scruggs instrumental is a blast to play on guitar. There are some spots that require some nimble string crossing with your pick hand. To tackle these tough spots you can start out by setting the overall difficulty level a bit easier, or you can set the difficulty level of individual measures. Remember to use the focus feature to practice the tougher measures or licks repeatedly.
Pickers tend to play this tune super fast, sometimes around 160 BPM. It's very tough to play at that speed, but there's something you can do do play faster, sooner: lower the difficulty level. It's easier to play less notes at a higher speed, than it is to play more notes at a higher speed. You can practice more difficult version with more licks at a slower speed and work on getting that up to your goal tempo as a more long-term project.
