Watch the Not Lazy online guitar lesson by Angus Clark from Essentials: Neoclassical Rock Soloing
As noted in the last example, Blackmore favors finding the root with his pinky on the 5th string, and the first lick in this example is no exception. This little repeater is a signature part of the solo on "Lazy" and it shows up elsewhere as well in the Blackmore catalog. It's easy and fun to play.
This is another descending progression in a minor key (hot tip!) which turns around on the V chord. The turnaround is a great opportunity for harmonic minor licks and/or diminished arpeggios licks.
