 Satriani has mastered many performance techniques on electric guitar, including legato, two-handed tapping and arpeggio tapping, volume swells, harmonics and extreme whammy bar effects.During fast passages, Satriani favors a legato technique (achieved primarily through hammer-ons and pull-offs) that yields smooth and flowing runs.He is also adept at other speed-related techniques such as rapid alternate picking and sweep picking.
