The guitar is a fretted musical instrument that usually has six strings.[1] It is typically played with both hands by strumming or plucking the strings with either a guitar pick or the finger(s)/fingernails of one hand, while simultaneously fretting (pressing the strings against the frets) with the fingers of the other hand. The sound of the vibrating strings is projected either acoustically, by means of the hollow chamber of the guitar (for an acoustic guitar), or through an electrical amplifier and a speaker.
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.
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.


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.
You need to place one finger on whatever fret you want to bar and hold it there over all of the strings on that fret. The rest of your fingers will act as the next finger down the line (second finger barring, so third finger will be your main finger, and so on). You can also buy a capo, so that you don't have to deal with the pain of the guitar's strings going against your fingers. The capo bars the frets for you. This also works with a ukulele.
For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is usual to play inverted chords on the guitar when they are not part of the harmony, since the bass guitar can play the root pitch.
Ze first began his journey playing original music and top 40s pop tunes around the country's popular venues. Eventually, through the music of John Mayer, he found a strong attraction to blues music. Ze has years of experience teaching beginners and intermediate guitarists. Currently with Liberty Park Music he is teaching Introduction to Guitar Playing for Complete Beginners, Rhythm Guitar to learn about strumming, chords and more, Guitar Essentials as a fast-track review course, and lots of Song Lessons on pop and rock hits.
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.
