Watch the Up a Flat 3: Alt. Dom. Sound online guitar lesson by Kenny Wessel from Shades of Jazz
This track features an F7b9b13 vamp. I'm playing an Ab minor pentatonic scale, which gives me all the altered notes: #9, #11, b13, b9 and a chord tone - b7. Almost any note that I land on in this scale is altered tension. I will also demonstrate the sound of an F minor pentatonic/blues scale over the F7alt chord so we can hear the difference between the two sounds. The F blues scale gives us the root, #9, 11, 5 and b7.
