The horizontal lines represent the frets on the guitar and the vertical lines represent the strings. The numbers listed let you know what fret number it is referring too. If there is an X it means don't play that string and if there is a 0 it means to play that string but do not press down on it anywhere. The black circles show you where to press down.
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.
Of course, there are a few ways to narrow down the string options. For starters, since guitars come in different scales, you need a set that's the right length for your instrument. You also need to match the type of guitar: electric strings for an electric guitar, acoustic strings for acoustic. If you play an acoustic-electric, you'll usually be looking for acoustic strings since those instruments use non-magnetic pickups. For classical and Latin guitar types directly descended from ancient gut-stringed instruments, the right strings are generally going to be nylon.
Learning to play other people's guitar solos is a great way to begin learning to write your own! Guitar teacher Nils B. shares his tips to learning four classic rock solos so you can develop your technique... An essential part of every musician's development is to imitate those who have already mastered their instrument. After settling on a song, give it a couple of close listens (preferably on headphones or a decent stereo), pick up a good transcription, then learn the rhythm parts, while an
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).
As previously stated, a dominant seventh is a four-note chord combining a major chord and a minor seventh. For example, the C7 dominant seventh chord adds B♭ to the C-major chord (C,E,G). The naive chord (C,E,G,B♭) spans six frets from fret 3 to fret 8;[49] such seventh chords "contain some pretty serious stretches in the left hand".[46] An illustration shows a naive C7 chord, which would be extremely difficult to play,[49] besides the open-position C7 chord that is conventional in standard tuning.[49][50] The standard-tuning implementation of a C7 chord is a second-inversion C7 drop 2 chord, in which the second-highest note in a second inversion of the C7 chord is lowered by an octave.[49][51][52] Drop-two chords are used for sevenths chords besides the major-minor seventh with dominant function,[53] which are discussed in the section on intermediate chords, below. Drop-two chords are used particularly in jazz guitar.[54] Drop-two second-inversions are examples of openly voiced chords, which are typical of standard tuning and other popular guitar-tunings.[55]

Archtop guitars are steel-string instruments in which the top (and often the back) of the instrument are carved, from a solid billet, into a curved, rather than a flat, shape. This violin-like construction is usually credited to the American Orville Gibson. Lloyd Loar of the Gibson Mandolin-Guitar Mfg. Co introduced the violin-inspired "F"-shaped hole design now usually associated with archtop guitars, after designing a style of mandolin of the same type. The typical archtop guitar has a large, deep, hollow body whose form is much like that of a mandolin or a violin-family instrument. Nowadays, most archtops are equipped with magnetic pickups, and they are therefore both acoustic and electric. F-hole archtop guitars were immediately adopted, upon their release, by both jazz and country musicians, and have remained particularly popular in jazz music, usually with flatwound strings.
Another chord you come across every day, the E major chord is fairly straightforward to play. Make sure your first finger (holding down the first fret on the third string) is properly curled or the open second string won't ring properly. Strum all six strings. There are situations when it makes sense to reverse your second and third fingers when playing the E major chord. 

As a general rule, brass strings are always going to be brighter than bronze strings. Though, counterintuitively, many brass strings go by the moniker of “80/20” bronze. These strings are actually the one in the same. Brass, or 80/20 bronze as it’s often known, is made from 80% copper and 20% zinc. This gives the strings a bright and cutting voice, though when used on guitars that already have a prominent high-end response it can make an instrument sound thin and tinny. For best results, use brass strings on a guitar that’s an OM size or larger (so this would include OM guitars, dreadnoughts, and jumbos).
The two most common types of acoustic guitar are the steel-string guitar and the classical guitar. The classical guitar, also known as the Spanish guitar, usually uses nylon strings. Steel-string guitars originated in the United States and are also referred to as western guitar and folk guitar. Steel-string guitars sound louder and brighter than classical guitars, which have a warmer, mellower sound. Steel-string models usually have larger bodies and narrower necks, and they often have a pickguard to protect the body against scratches by picks and fingernails. Most acoustic guitars have six strings, but there are also 12-string versions. When an acoustic guitar is hooked up to an amplifier, it is referred to as acoustic/electric. Some acoustic/electric guitars incorporate a cutaway design, which makes it easier for electric guitar players to cross over to acoustic.
