The bass guitar (also called an "electric bass", or simply a "bass") is similar in appearance and construction to an electric guitar, but with a longer neck and scale length, and four to six strings. The four-string bass, by far the most common, is usually tuned the same as the double bass, which corresponds to pitches one octave lower than the four lowest pitched strings of a guitar (E, A, D, and G). (The bass guitar is a transposing instrument, as it is notated in bass clef an octave higher than it sounds (as is the double bass) to avoid excessive ledger lines.[jargon]) Like the electric guitar, the bass guitar has pickups and it is plugged into an amplifier and speaker for live performances.
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]
The neck joint or heel is the point at which the neck is either bolted or glued to the body of the guitar. Almost all acoustic steel-string guitars, with the primary exception of Taylors, have glued (otherwise known as set) necks, while electric guitars are constructed using both types. Most classical guitars have a neck and headblock carved from one piece of wood, known as a "Spanish heel." Commonly used set neck joints include mortise and tenon joints (such as those used by C. F. Martin & Co.), dovetail joints (also used by C. F. Martin on the D-28 and similar models) and Spanish heel neck joints, which are named after the shoe they resemble and commonly found in classical guitars. All three types offer stability.

For experienced players, you already know what kind of questions need to be brought up when purchasing a guitar. For beginners, a great starting point is to look at what your favorite guitarists play. By taking your own musical tastes into consideration, you can narrow down your choices to models that will provide the tone and sound you already know and love. But whatever you're looking for, you can be certain that the perfect guitar for you can easily be found, right here. Just take a look around and see for yourself.

"Open" chords get their name from the fact that they generally include strings played open. This means that the strings are played without being pushed down at a fret, which makes chords including them easier to play for beginners. When you start to learn chords, you have to focus on using the right fingers to press down each note and make sure you're pressing the strings down firmly enough.
Some piezo-equipped guitars use a hexaphonic pickup. "Hex" is a prefix meaning six. A hexaphonic pickup produces a separate output for each string, usually from a discrete piezoelectric or magnetic pickup for each string. This arrangement lets on-board or external electronics process the strings individually for modeling or Musical Instrument Digital Interface (MIDI) conversion. Roland makes hexaphonic pickups for guitar and bass, and a line of guitar modeling and synthesis products. Line 6's hexaphonic-equipped Variax guitars use on-board electronics to model the sound after various vintage instruments, and vary pitch on individual strings.
On almost all modern electric guitars, the bridge has saddles that are adjustable for each string so that intonation stays correct up and down the neck. If the open string is in tune, but sharp or flat when frets are pressed, the bridge saddle position can be adjusted with a screwdriver or hex key to remedy the problem. In general, flat notes are corrected by moving the saddle forward and sharp notes by moving it backwards. On an instrument correctly adjusted for intonation, the actual length of each string from the nut to the bridge saddle is slightly, but measurably longer than the scale length of the instrument. This additional length is called compensation, which flattens all notes a bit to compensate for the sharping of all fretted notes caused by stretching the string during fretting.
The headstock is located at the end of the guitar neck farthest from the body. It is fitted with machine heads that adjust the tension of the strings, which in turn affects the pitch. The traditional tuner layout is "3+3", in which each side of the headstock has three tuners (such as on Gibson Les Pauls). In this layout, the headstocks are commonly symmetrical. Many guitars feature other layouts, including six-in-line tuners (featured on Fender Stratocasters) or even "4+2" (e.g. Ernie Ball Music Man). Some guitars (such as Steinbergers) do not have headstocks at all, in which case the tuning machines are located elsewhere, either on the body or the bridge.
The intervals between the notes of a chromatic scale are listed in a table, in which only the emboldened intervals are discussed in this article's section on fundamental chords; those intervals and other seventh-intervals are discussed in the section on intermediate chords. The unison and octave intervals have perfect consonance. Octave intervals were popularized by the jazz playing of Wes Montgomery. The perfect-fifth interval is highly consonant, which means that the successive playing of the two notes from the perfect fifth sounds harmonious.

The saddle of a guitar refers to the part of the bridge that physically supports the strings. It may be one piece (typically on acoustic guitars) or separate pieces, one for each string (electric guitars and basses). The saddle's basic purpose is to provide the end point for the string's vibration at the correct location for proper intonation, and on acoustic guitars to transfer the vibrations through the bridge into the top wood of the guitar. Saddles are typically made of plastic or bone for acoustic guitars, though synthetics and some exotic animal tooth variations (e.g. fossilized tooth, ivory, etc. ) have become popular with some players. Electric guitar saddles are typically metal, though some synthetic saddles are available.
UPDATE: SEPTEMBER 3rd, 2010 -- Good evening, and hi everybody! I get requests to add tabs once in a while, and for years one of the most common requests has been 'Psychic Hearts', and more recently 'Trees Outside the Academy'. I resisted for years, but boredom and the need to please has a funny way of making things happen, so I'm proud to bring you tabs for the entirety of "Psychic Hearts" and its related tracks, as well as the majority of "Trees Outside the Academy". I was originally planning on providing bass tabs as well as the Mascis solos, but I decided I wasn't that desperate for accolade. With all this attention on Thurston, I felt bad for Lee, so I've updated my outdated tab for his excellent solo acoustic piece "Here" (located under "Other Tabs") with the proper tuning, which also happens to be the tuning for the equally excellent "Lee #2", so I've updated that one too!
There are many different styles of play. Chords are played by strumming all of the strings. Classical guitarists pluck the strings with their fingers and always play sitting down. Slide guitarists slide along the strings with a slide made of metal or glass. Whether you're interested in classical, bluegrass, flamenco, folk or blues, the acoustic guitar is something you can enjoy playing alone or in a group.
