This version of Angelina Baker is played without a capo. We're playing the melody using some of the lower strings. IT can sound really great on guitar. To make those low notes cut in the mix of a jam, try and pick a little closer to the bridge.
You might not know it, but this song actually has lyrics! You might hear someone singing it at an Old-Time jam. It's usually played as an instrumental, and for whatever reason, it's most commonly played with the chorus melody first. Though that's not always true. The legendary Nashville Bluegrass band recorded this tune with the Verse melody in the A part just as it is here. Still, when in Rome, do as the Romans do!
