Watch the Chaconne Etude online guitar lesson by Angus Clark from Essentials: Neoclassical Rock Soloing
The first section of this etude is all about staying in time and being authoritative as you play these double stop unison bends. Attack!
The next section is all about thematic development while following the chords. The transition line uses the harmonic minor scale over the A7 chord in the key of D minor.
SWEEPS! These are the standard Yngwie style 5 string sweeps. D minor, Bb major, G minor (1st inversion), A7b9 (Bb diminished).
