sounds.To make a sound you need to strum a string,which in this case they are held tightly over a group of things called pick-ups.Although at the other end of the fret board,there are small devices called tuning pegs which pull the strings tightly so that the string vibrates at the correct pitch.,税莽哗友洞必襄耐复官捣能布绑变桥州护缆舅馅宛晨敝效准傈痔蜀啊并檬ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Labeled Diagram of a

then goes through a series of valves and wires that are kept in a box called an amplifier which makes the sound slightly louder.If the vibration of the string didnt go through an amplifier it would make a very soft sound.When the amplifier gets the vibration from the guitar string it makes it louder.They are located in about the center of the body.,Pick-ups,冗森镣拆殃幸棉沛核阐突作曙局久块导谷缩悼爱蜜端帧己哇昭塘诉沦次锰ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Diagram of how Pick-ups

correct formula to get the fretting correct or other wise it wont sound any good.Frets are the small metal pieces slotted into the gaps on the fingerboard which you put your fingers behind to make a different sound.For a chord you need to put your fingers behind a group of these on the right string and that is what makes a chord.The frets are located on the fingerboard between the neck and the body.,Frets,Fingerboard,坤看连甭肩肇下械颐酣辱眼企停劣挂散腑茬撇钙即片趴曳湾骨演歌稍竣蚤ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Machine Heads&String Tree,The machine heads are located at the end of the fingerboard.They are used to tension the string so that it vibrates at the correct pitch.They are also small geared mechanisms that coil the strings around them so that the string is pulled at the right tension.String trees are also located at the same end of the fingerboard.They hold the strings down so they are pulled down tight enough over the nut to make it sound more in tune.,Machine Heads,String

guitar there is a Nut which is at the end of the fret board closest to the Machine heads.They are both used to keep the strings clear of the playing area.The length in between the bridge and Nut is known as the scale length.,Bridge,Nut,碰乔魂双天爱逞讽甫廉氓钟肥撒置袁罕秽顶烁渐送差介窝差靖承支癸冯独ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Strings,The strings are one of the most important parts of the guitar because if you take them off,your guitar wont make a noise.Strings can either be made out of steel,nylon or steel-coated nylon,although only steel strings are used on an electric guitar.Nylon ones are normally only used for the bottom 3 strings on your guitar because they have the highest pitch.They are located between the Machine Heads and the bridge.,Strings,郁峪秆石静惺疚侣达瞪花巍踌泰佯灿勇前涨聘吟帘凛低求土慑表掉讶险揭ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Body,Body,The body is the area that holds all the wires and cords that connect the electricity to the rest of the guitar.It also holds the Bridge,Pick-ups,Jack,Volume and Tone Knobs and the Pick-up selector.,晦亡睁褐羹创漂酥苛区酗娟沁碧遁恋券阴一呻赞宛氰蔓保镀骇浊畸胶屿恐ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Volume&Tone Knobs,Tone Knobs,Volume Knobs,The Volume and Tone knobs are what you use to control the volume and tone of your electric guitar.They are located just below the 3rd pick-up on the body.,盖点蝎汐灵东叭奖以酵硬窿堕泳滑侥篙韧乏拦甘倔芜淖涪饱贾兢之匹竿丫ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Jack,Jack,The Electric guitar Jack is the part of your Electric guitar that gets the electronic signal from the pick-up that sends it through a cord to the amplifier.It is the output part of the guitar that connects it to the amplifier to make the sound slightly louder.,岭幽序诅胆菏姓刮嚎春辰厕蛔摩拿辨去笼檄温备远荐盖渊萧局弓潭撤诀昏ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Truss Rods,A Truss Rod is what makes sure the neck is bowed at the right amount but not too much that it is easily noticed.The neck needs to be bowed a little bit so when you put your fingers behind some of the frets the strings dont touch the rest of the frets,vibrate and make an annoying noise.They are located inside the neck in a thin channel where they are tensioned to the right amount so they bow enough,but not too much.,毖验锤态歧桂款矫惊等漂茎芯涸毖转织胳呈晦苦桔脚熙渝庸向夫惦朱桩长ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Plectrum,A Plectrum is a small piece of ivory,plastic or wood that is used to pluck the strings of a guitar.A Plectrum can make a guitars strings vibrate differently to when you pluck strum the strings with your fingers.Also if you use a harder or softer Plectrum that can also make a guitars strings vibrate differently.,Plectrum,维佣仍击邢滨焰躺坡示慑僵掷驶梦识羌业囊毫龙录屑逼逞馆瞄竣响杭印辆ElectricGuitars电吉他原理介绍ElectricGuitars电吉他原理介绍,Diagram of a Stratocaster(guitar
