This old-time tune has one of the catchiest melodies around! You'll find that because of the open strings and it being in the key of G, this arrangement is an easy one to get started...
Watch how the melody of the A section simply goes up and down the scale. Noticing melodic aspects like this can help in getting off the tab and moving towards full memorization.
Here's an arrangement with some great flow. Here's a tip: Before jumping right into the tab, push play and strum/chop along with the melody to get it in your head.
