* Whammy bar tricks. Van Halen was also known for his innovative use of the whammy bar, a lever that can be used to change the pitch of the strings. He used the whammy bar to create vibrato effects, dive bombs, and other sonic manipulations.
* Two-hand tapping. Van Halen also developed a technique called two-hand tapping, which involves tapping on the guitar neck with both hands simultaneously. This technique allowed him to create even more complex melodies and harmonies than with one-hand tapping.
* Fingerpicking. Van Halen was also a master of fingerpicking, a technique that involves plucking the strings with the fingers instead of a pick. Fingerpicking allowed him to create a more delicate and nuanced sound.
* Hybrid picking. Van Halen also used a hybrid picking technique, which involves combining pick playing with fingerpicking. This technique allowed him to create a wider range of sounds and textures.
