When you observe the tablature below, the first thing you'll notice is that there are a lot of slides. Sliding is a form of legato and is a technique you'll definitely need to master. The most important thing about slides is making sure the notes sustain properly when you're transitioning from one note to the next. If you don't apply the correct amount of pressure as you slide, the note could cut out. So make sure you apply just enough pressure to have the notes sustain during your slides.
