Found this on the Scott Henderson forum - posted by the man himself in response to a "Which books do you recommend” - type question
Thought it was worth sharing

I don't know of any books - sorry. Here are two exercises - pick any set of chord changes from the real book or wherever. Exercise 1 - pick any string and start from around the first fret. Play a chord tone for the first chord, and for the next chord, move up the string to the next chord tone. Continue like this through the tune all the way to the end of the neck and back. Exercise 2 - pick any chord tone on any string for the first chord. For the next chord, decide if you're already on a chord tone for that chord. If you are, you can stay there - if you're not, move to the closest one. Continue this through the tune.
