Before you start learning to play the guitar, view online video tutorials or ask other guitarists to show you clearly how to take the bar. Keep in mind, this technique you need to master necessarily, because it is the basis of the structure of many chords, and it needs to be used in some musical compositions. By the rote bar you will not need to move his hand far down the neck, just at the same time hold all or some of the strings on one fret.
Remember, there are 2 types the bar is large and small. In the first case, clamp five or all strings on a fret, and the second less than five strings. Do not worry if you have once failed. Daily practice. Start with the least complicated (small bar), and then gradually go to more complex (large bar). Keep in mind, the completion of the bar you can take months, so be patient and slowly keep training.
Sit back, relax your back and take up the guitar. The index finger hold down simultaneously several or all the strings on one fret and the other fingers lift above the fretboard. Hold the index finger straight and parallel with the metal nut Lada. And to provide him straighten and bend your arm in the wrist.
Be careful, the finger must not protrude above the top string. Other fingers hold the chord. At first it will seem complicated, but after a while your hands will get used to it, and you will succeed!
In order to take some bar chords, slightly bend your finger and place it at a slight angle in relation to the Lada. But before that, make your finger directly. If you are tired, take a break and begin working out again.
Remember, when you learn to play the guitar, you will easily be able to take the bar to clamp the strings and at the same time free to move the other fingers.
