If all guitarists did was play chords with a single strum or individually pick notes, the music industry - and guitar music - would be dead as we know it. Some of our favorite songs, both past and present, are so memorable because they vary the articulation of notes on the guitar. This means that rather than boringly stick with the same strumming pattern they include cool sounding tricks like pull-offs and hammer-ons.
If you want to improve your guitar playing skills and reall take your expertise to the next level, then watch this video on how to do hammer-ons on the guitar.
