This is a simple and effective Bluegrass solo. Lead-in notes are used to kick things off. They're also used in other spots where there's a big change in the melody. You can hear those notes are louder than others when you listen to and play along with the Tunefox player. These notes have accents that are listed in the tablature. They are marked with the less than sign ">". When playing those, simply pick a bit harder. Having strong lead in notes is important when taking a solo in a jam or band setting.
Follow the pick direction markings in the tablature. If you want to get fancy during those last 8 miles to Louisville, then check out the licks. There's lots of great ideas to explore and add in.
