The following licks will utilize the dominant 7b5 arpeggios and will resolve to an A blues sound.
Pay close attention to the tabs. These licks do not start on a downbeat. Lick 1 will begin on the "and" of 1 and Lick 2 on the "and" of 4.
These licks can be played as 8th notes or 16th notes. I encourage you to start slow and work your way up to 16ths.
