Vibrato Control

Vibrato is one of the most, if not the most, expressive tools that we
guitarists have in our arsenal of techniques. Continuous musical phrases
without the potent thrill of vibrato sound less dramatic than phrases with
the right vibrato used in the right places and situations. Classical
singers spend many years and a lot of effort trying to master vibrato with
their voice. Many guitarists, however, don't spend much time trying to
master this technique at all. Many guitar teachers either don't value
vibrato much themselves or just take the technique for granted and do not
stress the importance of vibrato enough to their students. It is
unfortunate that the value of possessing a great vibrato technique is often
underestimated.

I believe that the best and most expressive vibrato is slow to moderate
in speed but wide in range. There are times, however, when a somewhat
narrower range is needed (usually over slow and soft musical passages). A
fast vibrato can sometimes be effective, but use it with caution as it can
lead to an out of control sound (and an out of tune sound if you are not
careful). I very rarely use a fast or narrow vibrato and my vibrato is
never fast and narrow at the same time!

Here are the most common problems that many inexperienced guitarists
have with their vibrato technique:

• The vibrato is too fast. This sounds like a small annoying insect buzzing
  around your ears, and the note usually sounds out of control.
• The vibrato is too narrow in range. Unless you are playing in a slow and
  soft musical passage, this makes the note your playing sound weak and timid.
• Vibrato is not used enough. Notes decay too quickly and sound lifeless.
  This can cause the end of musical phrases to sound boring.
• Vibrato is being over used. Some players try to cram in vibrato at every
  possible chance they can. Overuse tends to lose its effectiveness on the
  listener.
• Vibrato is used either poorly or not at all on bent notes. When a string
  is bent the note will naturally decay more quickly without a strong vibrato
  to support it. If you don't already know this, adding vibrato to a note
  (especially a bent note) can drastically increase the life and sustain of
  the pitch.
• The vibrato is not in tune! (This one sounds really awful!) This is a
  common problem on bent notes and is caused by inconsistent bending of the
  string by the left hand (or the right hand if you play a left handed guitar.
  You must be careful to make sure that the string is being bent to the same
  place every time otherwise the pitch will be inconsistent and out of tune.
  Another cause of the note sounding out of tune is that the bent note is not
  being released (after each time that it is bent during the vibrato motion)
  to the exact same pitch every time. If you have this problem and are having
  a hard time solving it, I recommend to practice using an electronic tuner
  that has needle meter. Watch the needle and make sure that you are bending
  and releasing the note to the same place every time. It will help if you do
  a slower vibrato while practicing with the tuner.

I highly recommend listening to players that have an impeccable vibrato
technique. Here is a short list of virtuosos that have helped me to shape
my own vibrato: Yngwie Malmsteen, George Bellas, Andy LaRocque (plays in the
King Diamond band) and Jason Becker. There are, of course, other players
who I think have excellent vibrato too -s here are a few more guitarist's
vibratos to listen for: John Petrucci, Marty Friedman, George Lynch and Eddie Van Halen (on the older Van Halen recordings). A great vibrato technique usually takes a long time to master. It wasn't until after playing for many years that I felt that my own vibrato was where I wanted it to be. Finally, I'd like to suggest to you not to overlook or underestimate the importance and effectiveness of this highly expressive technique. Even after you master it, constantly work on it and continue to refine it always.
