Expressive techniques can add drama and excitement to your playing. One of the most common is the slur. A slur is a curved line above or below two or more different note. It indicates that the notes must be played smoothly (legato).
On the guitar, slurs are commonly achieved by the use of hammer-on's, pull-offs, slides and bends. If you are unfamiliar with these techniques, see Complete Learn to Play Lead Guitar Manual. Listen to the following example on the CD to hear the effect of slurs using hammer-on's and pull-offs.
