Watch the Duffy's Edge: 8 online guitar lesson by Chris Buono from Guitar Cubed
Guitar 2 brought to light the advantages of fingering natural harmonics with the underside of your fret hand fingers. If that were not the case you would definitely realize that fact right from the start of Guitar 3. Check out the pin-straight 3rd finger that’s used to play the 12th fret natural harmonics at beat 4 on the 5th and 1st strings (quite a span that would never happen if it were not for the fretting approach established in Guitar 2).
Another carry-over concept from Guitar 2 is proper arching for arpeggiated parts that rely on maximum ring such as the idea played at bars 9-11 and 13-15. Also, notice the use of the fret hand 3rd and 4th fingers and try to see why that’s the way to go before the secret is revealed in the breakdown. Back to the arch factor it’s a crucial component to making bars 19-20 and 23-24 ring true to form as well.
In the pair of preceding measures to the aforementioned bars watch for the rolling mutes and position shifts needed to nail the succession of perfect 4ths.
The final set of eight bars Guitar 3 rips through some Jimmy Page/Joe Perry sized unison bends (until the final top string octaves) that require a steady 1st finger no matter what string set you’re playing them on. All of this and more will be hashed out in the next segement.
