This is a piece that is assigned to students very early in their guitar playing development, typically. However, this is a difficult piece that Jason Vieaux wants to cover for more advanced level players. It has two lines playing at the same time, making the piece difficult. In the score, you will see a line with the stem up and a line with the stem down. He suggests playing one line at a time to practice, and then putting it together.
One thing to keep in mind is that our ears have the natural tendencies of listening in on the top line. In order to get the same kind of clarity in both lines despite this tendency, he emphasizes practicing the bass line alone. So when you play both together, you know exactly what the lower line sounds like even if you can’t hear too well. The idea is to train your ears to more actively hear the bass line. This is a great way to play any counterpoint, not only Bourrée .
Also in this video, Jason Vieaux makes a few fingering recommendations that he feels is helpful in extending the fingers.
