Ask any veteran musician, and they'll tell you that the early stages of learning a musical instrument go by a lot smoother when you're having fun. For this reason, Guitar Center strives their hardest to ensure every guitar lesson they offer is fully-engaging and an absolute blast for everyone involved. Whether you're into the warm, natural sound of an acoustic guitar or have aspirations of blowing out ear drums on the biggest stages in town, GC's guitar lessons are designed so that players of all ages, skill levels and tastes learn the chords and scales they need to know (and want to know) in a comfortable environment.
For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is usual to play inverted chords on the guitar when they are not part of the harmony, since the bass guitar can play the root pitch.
Piezoelectric, or piezo, pickups represent another class of pickup. These employ piezoelectricity to generate the musical signal and are popular in hybrid electro-acoustic guitars. A crystal is located under each string, usually in the saddle. When the string vibrates, the shape of the crystal is distorted, and the stresses associated with this change produce tiny voltages across the crystal that can be amplified and manipulated.

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]

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.
