All three principal types of resonator guitars were invented by the Slovak-American John Dopyera (1893–1988) for the National and Dobro (Dopyera Brothers) companies. Similar to the flat top guitar in appearance, but with a body that may be made of brass, nickel-silver, or steel as well as wood, the sound of the resonator guitar is produced by one or more aluminum resonator cones mounted in the middle of the top. The physical principle of the guitar is therefore similar to the loudspeaker.
The ratio of the spacing of two consecutive frets is {\displaystyle {\sqrt[{12}]{2}}} (twelfth root of two). In practice, luthiers determine fret positions using the constant 17.817—an approximation to 1/(1-1/ {\displaystyle {\sqrt[{12}]{2}}} ). If the nth fret is a distance x from the bridge, then the distance from the (n+1)th fret to the bridge is x-(x/17.817).[15] Frets are available in several different gauges and can be fitted according to player preference. Among these are "jumbo" frets, which have much thicker gauge, allowing for use of a slight vibrato technique from pushing the string down harder and softer. "Scalloped" fretboards, where the wood of the fretboard itself is "scooped out" between the frets, allow a dramatic vibrato effect. Fine frets, much flatter, allow a very low string-action, but require that other conditions, such as curvature of the neck, be well-maintained to prevent buzz.

Further simplifications occur for the regular tunings that are repetitive, that is, which repeat their strings. For example, the E-G♯-c-e-g♯-c' M3 tuning repeats its octave after every two strings. Such repetition further simplifies the learning of chords and improvisation;[71] This repetition results in two copies of the three open-strings' notes, each in a different octave. Similarly, the B-F-B-F-B-F augmented-fourths tuning repeats itself after one string.[73]
Am Strut Solo 1 is a free guitar lesson that will teach you how to play a blues solo over our original Am Strut jam track. Peter Vogl will show you how to use the Am pentatonic scale in the open position, the A natural minor scale, and some outside notes to create a solo. We’ll use hammer-ons, slides, and our right hand to create a more expressive solo. Specifically, we’ll use the thumb instead of a pick to play the strings and add a plucky and funky vibe. Peter will start by walking you through the theory choices and how to play the solo in detail. Next, we’ll practice the whole solo at a reduced speed with a metronome before advancing to playing along with the track. Sign up for a free 7 day trial and access a PDF of the tabs, a downloadable mp3 jam track, and three more solos over this progression.

Guitar chords are dramatically simplified by the class of alternative tunings called regular tunings. In each regular tuning, the musical intervals are the same for each pair of consecutive strings. Regular tunings include major-thirds (M3), all-fourths, augmented-fourths, and all-fifths tunings. For each regular tuning, chord patterns may be diagonally shifted down the fretboard, a property that simplifies beginners' learning of chords and that simplifies advanced players' improvisation.[70][71][72] The diagonal shifting of a C major chord in M3 tuning appears in a diagram.

Although many people thought rock and roll would be a passing fad, by the 1960s it was clear this music was firmly rooted in American culture. Electric guitarists had become the superstars of rock. Live performances in large halls and open-air concerts increased the demand for greater volume and showmanship. Rock guitarists began to experiment, and new sounds and textures, like distortion and feedback, became part of the guitarist's language. Jimi Hendrix was rock's great master of manipulated sound.
Almost all guitars have frets, which are metal strips (usually nickel alloy or stainless steel) embedded along the fretboard and located at exact points that divide the scale length in accordance with a specific mathematical formula. The exceptions include fretless bass guitars and very rare fretless guitars. Pressing a string against a fret determines the strings' vibrating length and therefore its resultant pitch. The pitch of each consecutive fret is defined at a half-step interval on the chromatic scale. Standard classical guitars have 19 frets and electric guitars between 21 and 24 frets, although guitars have been made with as many as 27 frets. Frets are laid out to accomplish an equal tempered division of the octave. Each set of twelve frets represents an octave. The twelfth fret divides the scale length exactly into two halves, and the 24th fret position divides one of those halves in half again.
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]
Open tuning refers to a guitar tuned so that strumming the open strings produces a chord, typically a major chord. The base chord consists of at least 3 notes and may include all the strings or a subset. The tuning is named for the open chord, Open D, open G, and open A are popular tunings. All similar chords in the chromatic scale can then be played by barring a single fret.[16] Open tunings are common in blues and folk music,[17] and they are used in the playing of slide and bottleneck guitars.[16][18] Many musicians use open tunings when playing slide guitar.[17]
First off, there are two more techniques I want to talk about. These are fret placement and finger posture. Place your first finger on the first fret of the B string. For fret placement, you’ll want to have your finger right behind the fret. In the video, you can see that the further away from the fret I place my finger, the more buzz the note has.
Flatwound strings have a flat surface. These strings are very popular among jazz guitarists because they have a very dark and understated tone. However, they are also more difficult to play. These strings are not a good fit for rock or blues, because they’re stiffness and dark tone means that it’s hard to cut through the mix and pull off the fast and intricate runs and bends that define blues, rock, and metal.
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.
What ultimately sets these rock guitar lessons apart from other offerings is the ability to submit a video for review using the ArtistWorks Video Exchange Learning® platform. Paul reviews each submission and records a video response, offering specific guidance to take your guitar playing to the next level. All students can access the Video Exchange library and watch each other’s interactions with Paul. This library is constantly expanding and may contain the key to unlock your playing.
The lower strap button is usually located at the bottom (bridge end) of the body. The upper strap button is usually located near or at the top (neck end) of the body: on the upper body curve, at the tip of the upper "horn" (on a double cutaway), or at the neck joint (heel). Some electrics, especially those with odd-shaped bodies, have one or both strap buttons on the back of the body. Some Steinberger electric guitars, owing to their minimalist and lightweight design, have both strap buttons at the bottom of the body. Rarely, on some acoustics, the upper strap button is located on the headstock. Some acoustic and classical guitars only have a single strap button at the bottom of the body—the other end must be tied onto the headstock, above the nut and below the machine heads.
Inlays are visual elements set into the exterior surface of a guitar, both for decoration and artistic purposes and, in the case of the markings on the 3rd, 5th, 7th and 12th fret (and in higher octaves), to provide guidance to the performer about the location of frets on the instrument. The typical locations for inlay are on the fretboard, headstock, and on acoustic guitars around the soundhole, known as the rosette. Inlays range from simple plastic dots on the fretboard to intricate works of art covering the entire exterior surface of a guitar (front and back). Some guitar players have used LEDs in the fretboard to produce unique lighting effects onstage. Fretboard inlays are most commonly shaped like dots, diamond shapes, parallelograms, or large blocks in between the frets.
When you play a guitar, bass, ukulele, mandolin or any other instrument in this big family, it's the vibration of the strings that creates your sound. That's common knowledge, of course, but have you ever stopped to really think about the implications? It's all too easy to dismiss your strings as just another part of your instrument, but the truth is they're more like its heart - and since playing the instrument means touching its strings, they also have a huge impact on the way it feels to play. With all that in mind, it's easy to see why the choice of strings is such an important one: it can make a massive difference in every aspect of your instrument, especially playability and tone. Picking out a new set of strings involves a number of choices, and those will depend on the specific instrument, so don't forget to filter the lineup by selecting a category. In most cases, that'll leave you with an easy-to-browse range of options - although if you're a guitarist or bassist, you'll still have hundreds to look at... and it might take a little more filtering to narrow things down further. Choosing your gauges will go a long way, not to mention material, which ranges from nylon for classical guitars to phosphor-bronze in acoustics and steel, nickel or even cobalt for electric guitars. Another aspect of strings to consider in your decision is coating. Traditional coated strings have a smoother feel than their uncoated cousins and usually last much longer, but they're also wider and that can make them sound different. If you like the idea of coated strings, but don't want to give up the tone you get with uncoated ones, then check out Elixir and Cleartone strings: these two manufacturers have mastered the art of ultra-thin, "barely-there" coatings that behave more like traditional strings. We've only just scratched the surface of what's available in this section, and there's a lot to see no matter what instrument you play. Different materials and gauges, coated or uncoated - it's up to you. You can buy your strings one at a time, go for a set or even stock up with multiple sets of strings at once. Still not sure where to begin? Try starting with the top-selling and best-rated strings and go from there. Finding the perfect set will probably take some experimentation, but there's no better guide than other musicians to get you on the right track.

Jump up ^ "We know from literary sources that the five course guitar was immensely popular in Spain in the early seventeenth century and was also widely played in France and Italy...Yet almost all the surviving guitars were built in Italy...This apparent disparity between the documentary and instrumental evidence can be explained by the fact that, in general, only the more expensively made guitars have been kept as collectors' pieces. During the early seventeenth century the guitar was an instrument of the people of Spain, but was widely played by the Italian aristocracy." Tom and Mary Anne Evans.

The types and models of pickups used can greatly affect the tone of the guitar. Typically, humbuckers, which are two magnet-coil assemblies attached to each other, are traditionally associated with a heavier sound. Single-coil pickups, one magnet wrapped in copper wire, are used by guitarists seeking a brighter, twangier sound with greater dynamic range.
A six-string guitar has five musical-intervals between its consecutive strings. In standard tuning, the intervals are four perfect-fourths and one major-third, the comparatively irregular interval for the (G,B) pair. Consequently, standard tuning requires four chord-shapes for the major chords. There are separate chord-forms for chords having their root note on the third, fourth, fifth, and sixth strings.[41] Of course, a beginner learns guitar by learning notes and chords,[42] and irregularities make learning the guitar difficult[43]—even more difficult than learning the formation of plural nouns in German, according to Gary Marcus.[44] Nonetheless, most beginners use standard tuning.[45]
For the second note of the A minor 7 chord, place your second finger on the second fret of the D string. This is the second of the two notes you need to fret to play this chord. Make sure you’re on the tip of your finger and right behind the fret. Now that you have both notes in place, strum the top five strings, remembering to leave the low E string out.

Once you've got your categories narrowed down, then you can start getting into the nitty-gritty differences between strings. For instance, electric guitars will give you the choice between nickel (for authentic vintage sound) and stainless steel (for maximum durability). Some string manufacturers have exotic material options with their own unique characteristics, like Ernie Ball's Slinky Cobalt strings. With so many subtle differences separating guitar strings, you owe it to yourself to browse carefully and look at all the choices on the table before making a decision.
Unlike a piano or the voices of a choir, the guitar (in standard tuning) has difficulty playing the chords as stacks of thirds, which would require the left hand to span too many frets,[40] particularly for dominant seventh chords, as explained below. If in a particular tuning chords cannot be played in closed position, then they often can be played in open position; similarly, if in a particular tuning chords cannot be played in root position, they can often be played in inverted positions. A chord is inverted when the bass note is not the root note. Additional chords can be generated with drop-2 (or drop-3) voicing, which are discussed for standard tuning's implementation of dominant seventh chords (below).
