Justin, first off I just wanted to say thanks for all the advice and instruction. You make playing guitar easy and understandable and fun. You explain very well the hows and whys when presenting a new song to learn and walk it through so that anyone can learn. I have played guitar for 20 years now and have learned more from you in the last five years than the previous 15 by myself. You have also been a tremendous help to both my son and my daughter in learning to play as well by making playing fun and interesting. I have a couple of pictures of me and my children all doing what we love. Many Thanks to you Justin
You need to place one finger on whatever fret you want to bar and hold it there over all of the strings on that fret. The rest of your fingers will act as the next finger down the line (second finger barring, so third finger will be your main finger, and so on). You can also buy a capo, so that you don't have to deal with the pain of the guitar's strings going against your fingers. The capo bars the frets for you. This also works with a ukulele.
Guitars have been played since the Renaissance era, after descending from the ancient Greek instrument, the kithara. Or, at least, that's how the theory goes: the only real proof for this is the similarities between the Greek word and the Spanish word, quitarra. Early guitars often had four strings, evolving into the six-string version we know today in the late 1600s. Anton Stradivari, the famous violin-maker, also had a hand in making guitars. There's now only one Stradivarius guitar left in existence.
