This blog is dedicated to the idea that learning and playing guitar should be as fun as possible. It is a fine read if you are starting to learn guitar from scratch and if you tend to search for ways to be more creative.
Learn guitar and have fun too.
Pretty much everyone I know can imagine what a mother does for a baby when he is crying. She rocks him back and forth, and usually (although not intentionally) in a rhythmic manner. I can't prove it, but I really do have a strong hunch that the sensations we pick up on as children is directly correllated to the way we, as adults, perceive rhythm. That rhythmic motion is soothing to a child, somehow just as the beat or the rhythm of a song is soothing to adults. Just like a heartbeat, too. Therefore, as my hunch goes, breaks or gaps in the rhythm are far more distracting than playing wrong chords.
When it comes to playing guitar, again, I would rather hear someone play the wrong chord and the right rhythm, as opposed to the right chord and the wrong rhythm. One of the things that happens to people when they first start playing guitar is that they often will neglect the rhythm in favor of playing or in striving to play the correct chord. This is jarring. Yes it is important to play the right chord. Yes it is important to strive to play "correctly" (if that's the desired outcome, of course). But no, it's not so important to neglect the rhythm for the right chord.
Rhythm in music is soothing to adults like rhythmic patterns (like rocking, or hearing a heartbeat) are soothing to babies. So if the chord is wrong, I won't care. Just as long as the rhythm is there, my suggestion is to smile and keep playing. That's advice given to me from many dance teachers.
