As with most chords in this list, a clear G major chord depends on curling your first finger so the open fourth string rings clearly. Strum all six strings. Sometimes, it makes sense to play a G major chord using your third finger on the sixth string, your second finger on the fifth string, and your fourth (pinky) finger on the first string. This fingering makes the move to a C major chord much easier.
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.

A slide, (neck of a bottle, knife blade or round metal or glass bar or cylinder) is used in blues and rock to create a glissando or "Hawaiian" effect. The slide is used to fret notes on the neck, instead of using the fretting hand's fingers. The characteristic use of the slide is to move up to the intended pitch by, as the name implies, sliding up the neck to the desired note. The necks of bottles were often used in blues and country music as improvised slides. Modern slides are constructed of glass, plastic, ceramic, chrome, brass or steel bars or cylinders, depending on the weight and tone desired (and the amount of money a guitarist can spend). An instrument that is played exclusively in this manner (using a metal bar) is called a steel guitar or pedal steel. Slide playing to this day is very popular in blues music and country music. Some slide players use a so-called Dobro guitar. Some performers who have become famous for playing slide are Robert Johnson, Elmore James, Ry Cooder, George Harrison, Bonnie Raitt, Derek Trucks, Warren Haynes, Duane Allman, Muddy Waters, Rory Gallagher, and George Thorogood.
This book is smaller than I thought it would be, but it's fairly thick. The book is 6.5 inches wide, 9.5 inches 'tall', and slightly more than 1 inch thick. It is not spiral bound and so it does not lay flat very well at all. After I located a song that I wanted to play, I tried to force the book to lay flat by pushing down on the spine. It didn't help much and it is frustrating when the book wants to close while you're reading it. I might have to take it somewhere to have it spiral bound. The songs are listed in alphabetical order which makes it easy to find the song you're looking for if you know the title. And here is the part that surprised me: The book contains lyrics, chord diagrams, and chord names "only". It ... full review
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.
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.

Unlike the piano, the guitar has the same notes on different strings. Consequently, guitar players often double notes in chord, so increasing the volume of sound. Doubled notes also changes the chordal timbre: Having different "string widths, tensions and tunings, the doubled notes reinforce each other, like the doubled strings of a twelve-string guitar add chorusing and depth".[38] Notes can be doubled at identical pitches or in different octaves. For triadic chords, doubling the third interval, which is either a major third or a minor third, clarifies whether the chord is major or minor.[39]
