A. Touching the wrong strings when you play chords is a common
problem that many beginners face when learning the guitar. Today we
will look at some simple solutions.
 
1. Try and press your fingers straight down. Your finger should be
at a 90 degree angle with the string. This means that only the tip
of your finger should be connecting with string.

2. Are your fingernails short? If your fingernails are long, your
fingertip will not be able to sit on the string and your fingers
will touch the other strings on the guitar.

3. Place your thumb directly on the back of the neck of your
guitar. This puts your hand in a good position to keep your fingers
clear of the wrong strings.

4. Practice with chords you find easy. Look at how your hand sits
when you play these chords. Try to use the technique that you use
on easier chords with more difficult chords.

5. Using a capo at higher frets can make it easier on your fingers
as the frets are closer together. However for people with big hands
this can make it more difficult. So experiment with a capo to see
if it helps you.

Each person has different size hands, finger shape and flexibility.
For this reason there is no universal rule that will change your
playing to avoid touching the wrong strings when playing. You
should practice chords as much as you can until you feel confident
and comfortable with them.
