Watch the Voice Leading in Position 4 online guitar lesson by Jason Loughlin from Blues Connections: Minor
For this example, we'll voice lead over a 12-bar blues in A minor. I'm using mode 4 in A minor which puts me on the 5th, mode 2 in D minor which puts me on the b3rd, and mode 1 in E minor which puts me on the root. This will make sure I stay in or around the same position. Take a second and review these modes. Take note of what notes they share and which ones are different. Also, start to map out your root, b3rd, and 5th.
