The black dots found on the chord diagrams tell you which fret to press down, and on which string and with which numbered finger. Additionally, you will sometimes see circles above the nut. These circles tell you to play that open string without pressing any fret. So using what we know so far about strings, finger numbers, and dots, let’s check out that same chord diagram again:
I bought this because I wanted to learn more AC/DC songs note for note as they're fun and not overly complicated. This book doesn't disappoint. With the little time I've had to practice so far, this book's been a great help, and for a lot cheaper than most song books. For best accuracy it helps to listen to the songs too. My only gripe is "Have a Drink on Me" isn't included.
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.
Picks come in many shapes and sizes. Picks vary from the small jazz pick to the large bass pick. The thickness of the pick often determines its use. A thinner pick (between 0.2 and 0.5 mm) is usually used for strumming or rhythm playing, whereas thicker picks (between 0.7 and 1.5+ mm) are usually used for single-note lines or lead playing. The distinctive guitar sound of Billy Gibbons is attributed to using a quarter or peso as a pick. Similarly, Brian May is known to use a sixpence coin as a pick, while noted 1970s and early 1980s session musician David Persons is known for using old credit cards, cut to the correct size, as plectrums.
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.
The original purpose of the resonator was to produce a very loud sound; this purpose has been largely superseded by electrical amplification, but the resonator guitar is still played because of its distinctive tone. Resonator guitars may have either one or three resonator cones. The method of transmitting sound resonance to the cone is either a "biscuit" bridge, made of a small piece of hardwood at the vertex of the cone (Nationals), or a "spider" bridge, made of metal and mounted around the rim of the (inverted) cone (Dobros). Three-cone resonators always use a specialized metal bridge. The type of resonator guitar with a neck with a square cross-section—called "square neck" or "Hawaiian"—is usually played face up, on the lap of the seated player, and often with a metal or glass slide. The round neck resonator guitars are normally played in the same fashion as other guitars, although slides are also often used, especially in blues.
Pickups are transducers attached to a guitar that detect (or "pick up") string vibrations and convert the mechanical energy of the string into electrical energy. The resultant electrical signal can then be electronically amplified. The most common type of pickup is electromagnetic in design. These contain magnets that are within a coil, or coils, of copper wire. Such pickups are usually placed directly underneath the guitar strings. Electromagnetic pickups work on the same principles and in a similar manner to an electric generator. The vibration of the strings creates a small electric current in the coils surrounding the magnets. This signal current is carried to a guitar amplifier that drives a loudspeaker.
Guitar Chords are a group of at least 3 notes played together, this means three different notes, i.e. notes with 3 different pitches. If, for example, you select an E major chord on the guitar chord generator on this page, you can see the 3 notes E, B and G# (Ab) make up this chord. Some notes can be expressed as either sharp or flat (enharmonic spelling), the notes sound just the same but the naming of them is decided by which key the song is in. You can find out more about this in our music theory section.
As you start practicing, your fingers may be sore for a while, but that will pass with four to six weeks. One thing I want to warn you about is that new guitar players can get frustrated when they can’t play clean chords because they try to switch between chords too soon. Often, they try to switch chords before they’ve really learned and memorized each chord shape. For now, don’t worry about switching chords and just work on each shape, getting them down, and going right to them.
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).

Unlike many string instruments which use a bow to create a sound, guitars are played by plucking or strumming the strings on the instrument, which vibrate to create a sound. Chords are played when the guitarist holds their fingers down on more than one individual string to change its length, which in turn changes the frequency of the vibration created - in other words, it creates a different note. Performers often use guitar tabs, rather than sheet music, when learning music: this acts as a kind of 'map' to teach guitarists where to put their fingers on the strings.
