Grammy winner Jason Vieaux lectures and demonstrates his methods of ornamentation in the music of Baroque composer Johann Sebastian Bach (1685-1750). This comes via the GFA Channel on YouTube. Nice video with the music notation below, dang I have to step up my game obviously! You can also check out the lesson by Scott Morris on Baroque Ornamentation on Classical Guitar which will give you more info.
