Watch the The 6 Arpeggio online guitar lesson by Brad Carlton from Blues Bass

This lesson presents the (major) 6 arpeggio as a source for bassline construction. The formula for a 6 arpeggio is: 1, 3, 5, 6. Diagrams 3a and 3b show this arpeggio laid out on the fingerboard. You will use these two forms to play through the 12 bar blues progression in the key of G. Feel free to experiment with variations of these four chord tones. Here are some suggested variations: 1 3 5 6, 1 3 6 5, 1 5 3 6, 1 5 6 3, 1 6 3 5, and 1 6 5 3. You will notice that I did not use the 8 in these variations. After you can play the six variations that I've suggested, then experiment with using the 8 in place of any of the chord tones except the root(1).

In case you were wondering why we are able to use a 6 arpeggio over a 7 chord, the answer is that the 6 is an extension of the 7 chord. The next lesson will address this.
