Keep your guitar in tune? lol
It sounds stupid but I'm serious. If you have a tuner use it! If not try to get the low E string to an E somehow and tune to major 4th up on each following string. If you don't know what a major fourth is it's do to fa on a basic solfege scale. When you play the two strings you should be able to hear the notes used in the melody of 'here comes the bride.'
... that is a really complicated method of tuning a guitar. o-o
My guitar teacher taught me how to do it by ear... maybe you could find out how to do it on Youtube?
Uh I know that you can get a poster with guitar chords on it from places. I bought mine from Walmart but you can get them at my local music store too... just try to find one somewhere. xD
But if your guitar isn't in tune then it will sound as it would if crap had sound.
So you definitely need to do that first. xD
