The modern word guitar, and its antecedents, has been applied to a wide variety of chordophones since classical times and as such causes confusion. The English word guitar, the German Gitarre, and the French guitare were all adopted from the Spanish guitarra, which comes from the Andalusian Arabic قيثارة (qīthārah)[4] and the Latin cithara, which in turn came from the Ancient Greek κιθάρα (kithara).[A] which comes from Persian word Sihtar. We can see this kind of naming in Setar, Tar, Dutar and Sitar. The word "Tar" at the end of all of these words is a Persian word that means "string".[6]
Justin Sandercoe has thought long and hard about how to teach people to play the guitar, and how to do this over the internet. He has come up with a well-designed series of courses that will take you from nowhere to proficiency. I tried to learn how to play years ago, using books, and got nowhere. I've been using Justin's site for just over a year and I feel I've made real progress. What's more, Justin offers his lessons for free - a boon for any young player who has the urge to play, but whose pockets are empty. I've seen and used other sites for learners: none of them offer as clearly marked a road as Justin does.

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.
