For example, in the Star Spangled Banner, the song is played by picking notes on different strings, with a mixture of varying effects, depending on the version of the song. The notes are picked in the order in which they appear from left to right. If you continue to hold the fret down after the slide, or even after picking any random note, it will cause the note to ring. This effect is called vibrato. Each of these effects is symbolized by a different character on the tab.
Bends are relatively easy to perform.
A rake is simply when you scratch the pick across the strings, or even your fingers. This effect causes the guitar riffs to sound muffled and choked. To produce this result, keep part of your palm on the strings right by the bridge where they connect to the base of the guitar. This will produce a dull, almost scratchy sound. A good example of this effect is in Everclear s song, Santa Monica.
