String Bending Technique
String bending is a basic blues and rock technique. The idea is to "bend" (push a string across or over the fingerboard with your left-hand fingers) so that the string gets tighter and the pitch goes up.
It is very important to practice this as it sounds awful when done badly. In fact, if your guitar is in tune, it is very hard to play a note out of tune, unless you bend. If you don't practice bending in tune right away you will risk sounding like a child learning violin, not something you should inflict on your friends or family, or a paying audience :)
This is a very hard technique to teach using only text, so try and watch the video for this lesson a few times.
1. Always use two or more fingers (usually your second and third fingers). At more advanced stages you may use only one finger, but only if two are not available (or if you do a first finger bend).
2. Try to use your wrist to make the bend and use your fingers as levers. As you work on the technique you should find that it feels very easy when you do it right and very hard to do if you have the technique wrong!
3. When practising always hold the bent note to check that it is properly in tune (the most important aspect of bending practice).
To practice bends as shown, use the same finger throughout- usually your 3rd finger.
Play the note you want to bend followed by the note you want to bend to. Then play the original note again and bend it to the pitch of the second note. This will improve your intonation (get you in tune).
Some teachers recommend using a guitar tuner to work on getting it in tune, not a bad idea, but I think that it is better to use your ears - you won't be using a guitar tuner on stage!
Once you feel comfortable with the technique and it feels easy you should start to work on your vibrato. The "pro" approach is let the note ring pure before adding the vibrato on after a small amount of time.
Listen to the blues masters and try and emulate them. Try and develop the feeling that you can make the guitar sound and way that you hear it!
You should also practice "fast bends" where the note is not held for long at all (Chuck Berry is a good example of this technique), and very slow bends that are held for a long time (like say Dave Gilmore).
Bends are great to experiment with and some very unusual effects can be obtained by getting creative with them. Try bending fast and slow, try ghosts (where you start with it bent before you play it) Double bends, two string bends, bending big intervals (like two tones - 4 frets), bend and then using tapping... it goes on. There is a lot to experiment with in this technique, some of which will be covered later, but you can go and explore all by yourself too!
