Links for Approach Tones

Here are a couple of links to more info on using approaches to chord tones in your solos:

1. A detailed post from a guitar forum (I know, just pretend it isn't) about various approach tones and using chord tones as targets.
   
2. A supposed Mike Stern lesson on approach tones. Written in god-awful brain damaging tab for your mental anguish, but it re-enforces some of the stuff about approach tones and shows a few more kinds.
   
3. This one has notation and a midi file.
