Watch the Dominant Flat 13th online guitar lesson by Frank Vignola from Next Steps Jazz: 2-5-1 Progressions
Almost the exact same fingering as the dominant 13th we just learned except that the pinky is moved back one fret making the 13th flatted. This 5 chord is great to add tension before going back to a 1 chord. It'll be great to hear it resolve! Move it up and down the fretboard and have fun with this sound.
