Hi, digging into this section, and even went over to the “jazz up your blues” lesson from young Justin. Can you provide an example of the following Exercise noted in this lesson:
Exercise
A great exercise is to analyze a solo by a guitar player you like. You should observe every note played concerning the chord played over it.
Sultans Of Swing by Dire Straits is a good song if you can’t make a choice! 
I used to do this a lot! I’d transcribe a solo in tab and notation and write the chords above the notes. Then, I’d identify the relationship between each note and the chord played over (like 2, b3, 5, b7, 5, #5, 6, etc., and write it underneath the notes in red pen.
When you do this type of harmonic analysis, you will grow as a player by examining note choices more constructively. You’ll start to fill your head with cool concepts that you can use in your playing!
Hi David,
If you are more on the beginner side, I’d suggest you choose an easier solo, e.g. Day Tripper by The Beatles. It’s much shorter and there are repetitions in it, the tempo is slower, and there are only a handful of chords in the song.
If you can transcribe the opening riff, you can get a good idea about the key of the song (i.e. which chords to expect). Focusing on the root notes of the chords (often played by the bass) can be a good starting point.
Then, transcribe the solo (or part of it) and check what notes are played over what chord. For example (not in the Beatles song), if there’s a sequence of, let’s say, G-G-D-Bb-G-G-D-Bb over a Gm chord, you would mark the notes as R (root)-R-5-b3-R-R-5-b3.
But it may happen that a chord is non-diatonic, i.e. not part of the key the song is written in; or that non-diatonic notes are played in the solo (or sung).
Start out small and when you get enough experience/confidence, tackle longer or more complex solos and chord progressions.
