Watch the Darker Tension online guitar lesson by Sheryl Bailey from 50 Essential Bebop Licks You MUST Know
An important sound to the II-7 V7 I cadence is to begin to add the b9 sound on the dominant 7. By adding this dark color you create more tension for a stronger release on the resolution to I. This example again combines Cmin7 and Amin7b5 on the II-7, then uses a Gbo7 arpeggio on the F7, to create a dominant 7b9 sound. You could think of it as substituting a Dim7 arpeggio up a half from the root of the dominant to create that beautiful dominant 7b9 sound. This sound is a core to jazz playing of all styles.
