Watch the JAM: Incorporating Bass Lines online guitar lesson by Susan Mazer from Hands On Guitar: Beyond Beginner
You’ll notice that this tune is in ¾ time, so it has a bit of a country feel. It uses both slash-chords and single notes to create a bass line. For example, the second measure leads us from a “C” chord up the scale through “D” and “E” notes, until we reach the “F” chord. It also has a swing feel. You'll hear that I'm playing the strumming pattern with a bit of a bounce.
