So far we’ve used phrases that follow the natural movement of the A H/W diminished scale. This is great to get you started with seeing and hearing V to I resolution, but we can take this beyond scales and start integrating diminished 7^th arpeggios. 

As you might recall from Module 1 and 2, a dominant 7(♭9) chord is a dominant 7^th and a diminished 7^th chord combined: 

We therefore know that a diminished 7^th arpeggio is a solid choice over a dominant 7^th chord. But how do we find the right arpeggio quickly and over any V chord?  

The trick that most people start with is locating the major 3^rd and playing from there: 

This gives us an A7(b9) sound, and just like our first exercise, you should be able to see the B♭ wants to resolve down a fret. 

Here’s a very basic lick idea that starts with a bluesy pickup, then resolves to the D chord: 

Just like our previous exercises we can easily shift this idea around in minor 3rds, so check out the example solo for ideas on how to navigate around the neck.
