Practice string bending
How to practice string bending 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.
