Electric guitars and bass guitars have to be used with a guitar amplifier and loudspeaker or a bass amplifier and speaker, respectively, in order to make enough sound to be heard by the performer and audience. Electric guitars and bass guitars almost always use magnetic pickups, which generate an electric signal when the musician plucks, strums or otherwise plays the instrument. The amplifier and speaker strengthen this signal using a power amplifier and a loudspeaker. Acoustic guitars that are equipped with a piezoelectric pickup or microphone can also be plugged into an instrument amplifier, acoustic guitar amp or PA system to make them louder. With electric guitar and bass, the amplifier and speaker are not just used to make the instrument louder; by adjusting the equalizer controls, the preamplifier, and any onboard effects units (reverb, distortion/overdrive, etc.) the player can also modify the tone (aka timbre or "colour") and sound of the instrument. Acoustic guitar players can also use the amp to change the sound of their instrument, but in general, acoustic guitar amps are used to make the natural acoustic sound of the instrument louder without changing its sound that much.
With that being said, nickel strings definitely have a richer tone with more body than steel strings. This warmth is especially pleasing when used to play older genres of music, blues in particular. The strings are also a great fit for rhythm work, because the warmth inherent to these strings helps to increase the overall body and richness of a mix.
Quartal and quintal harmonies also appear in alternate tunings. It is easier to finger the chords that are based on perfect fifths in new standard tuning than in standard tuning. New standard tuning was invented by Robert Fripp, a guitarist for King Crimson. Preferring to base chords on perfect intervals—especially octaves, fifths, and fourths—Fripp often avoids minor thirds and especially major thirds,[102] which are sharp in equal temperament tuning (in comparison to thirds in just intonation).

Before the development of the electric guitar and the use of synthetic materials, a guitar was defined as being an instrument having "a long, fretted neck, flat wooden soundboard, ribs, and a flat back, most often with incurved sides."[2] The term is used to refer to a number of chordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas.[3] A 3,300-year-old stone carving of a Hittite bard playing a stringed instrument is the oldest iconographic representation of a chordophone and clay plaques from Babylonia show people playing an instrument that has a strong resemblance to the guitar, indicating a possible Babylonian origin for the guitar.[2]

Welcome to video eight in the Beginner Guitar Quick-Start Series. In this lesson, we’re going to go through your first two chords. You’ll learn A minor 7 and C major. These two guitar chords will be useful for you because you’ll be using them often through your guitar career. A minor 7 is good to start with because it is fairly easy, and C major is great chord to learn how to play clean sounding chords.


The fingerboard, also called the fretboard, is a piece of wood embedded with metal frets that comprises the top of the neck. It is flat on classical guitars and slightly curved crosswise on acoustic and electric guitars. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which the fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Most modern guitars feature a 12" neck radius, while older guitars from the 1960s and 1970s usually feature a 6-8" neck radius. Pinching a string against a fret on fretboard effectively shortens the vibrating length of the string, producing a higher pitch.
The electric guitar initially met with skepticism from traditionalists, but country and blues players and jazz instrumentalists soon took to the variety of new tones and sounds that the electric guitar could produce, exploring innovative ways to alter, bend and sustain notes. The instrument's volume and tones proved particularly appealing to the enthusiasts of rock and roll in the 1950s.
"With a note of music, one strikes the fundamental, and, in addition to the root note, other notes are generated: these are the harmonic series.... As one fundamental note contains within it other notes in the octave, two fundamentals produce a remarkable array of harmonics, and the number of possible combinations between all the notes increases phenomenally. With a triad, affairs stand a good chance of getting severely out of hand."

Paul Gilbert has made Guitar World's "50 Fastest Guitarists of All Time", and his guitar shredding is legendary. Paul picked up his first guitar when he was 5 years old. By the time he was 15, he was featured in Guitar Player magazine. After graduating from the Guitar Institute of Technology (GIT) in Los Angeles, Paul immediately joined the faculty as a guitar teacher. While teaching, he formed the band Racer X and Grammy-nominated group Mr. Big. Paul breaks down his iconic playing techniques and practice drills. He's known for his enthusiastic and approachable guitar lessons, which are founded on decades of experience.
Another factor to consider are the alloys used to make the string. Acoustic strings may be phosphor bronze or an 80/20 bronze/zinc alloy, electric strings may be pure steel or a steel/nickel alloy, and the outer winding on the thicker strings may be either round wound or flat wound, which is typically used by jazz guitarists for smooth fingering with less fretting noise. Acoustic and electric strings are both now available with special super-thin coatings to protect them from sweat and corrosion. Coated strings cost more, but generally last much longer. Find out what type of string your favorite player uses, try guitars with different types of strings at your local guitar store, then try a few different sets on your guitar to see what feels and sounds best for your playing style. Major manufacturers include Ernie Ball, Martin, GHS, D'Addario, and Elixir, among others. Make sure you have a string winder to make installing the strings go faster, and some pliers with a fine wire cutter to clip the excess string from the tuning post, a well as some guitar polish - changing strings is a good time to perform some routine maintenance. Keep a clean cloth in your case to wipe down the strings after each use, along with extra bridge pins for your acoustic guitar. Regular string changes are the best way to keep your tone crisp and clear, so grab a pack and tune 'em up!
A chord is inverted when the bass note is not the root note. Chord inversion is especially simple in M3 tuning. Chords are inverted simply by raising one or two notes by three strings; each raised note is played with the same finger as the original note. Inverted major and minor chords can be played on two frets in M3 tuning.[56][74] In standard tuning, the shape of inversions depends on the involvement of the irregular major-third, and can involve four frets.[75]
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.
