In this video, we learn how to play blues guitar: a sliding 9th chord. First, play a G9 chord, where you will here all of the chords around it as you play. You can slide this chord around one or two frets to hear different sounds come from it. It's a great vehicle to slide up and down. You can also use the fifth string to go up and down, which will create a more funky sound while playing. Use the four and five chords for the most interesting sounds. You can also put the fifth in the bass to make it heavier and have more drama as well!
