Betcha Can't Play This: Chris Broderick's Arpeggio Etude
“This first lick [FIGURE 1] is an arpeggio etude [musical-sounding exercise] in A minor that integrates tapping, multiple hammer-on and pull-off combinations and a little bit of economy picking into a steady stream of 16th notes. It pretty much stays within the realm of the A minor pentatonic scale [A C D E G], with the flatted fifth, Eb, added in the last two bars.
