Watch the Whammy Bar online guitar lesson by Jennifer Batten from Rock Sauce for Rhythm Guitar
This groove has a metal attitude but an unusual chord structure beyond a basic power chord. This chord is a root, major third and minor seventh which forms a dominant chord. The two chords are the same voicing but played a whole step apart. I use the tremolo bar to bend the strings while sliding from chord to chord. I also bend the strings with the bar between two natural harmonic chords.
