Watch the Buckdancer's Choice online guitar lesson by Matthieu Brandt from Modern Mountain Banjo: Clawhammer & Up-Picking
"Buckdancer's Choice" is a mixture of a simple major melody with basic chords. It has an old-timey feel with kind of a happy sounding foot tapping groove, so it's good to dance to.
I've inserted some bluesy twists in the form of dominant seventh chords and a Mixolydian melody, just too keep it fresh to the ear. You can use these bluesy tricks in your own arrangements of standard old time songs, if you like. Another thing we're doing is stressing the harmony, by playing the roots of the chords whenever we can. This gives a tune a nice chunky feel, even if you're playing it by yourself.
