Materials used for making a bass guitar

The bodies of these special instruments are typically made of wood although other materials such as graphite have also been used. The most common type of wood used for the body is alder, for the neck is maple, and for the fret board is rosewood, though a wide variety of woods may be used to make the body.

Other regularly used woods include mahogany, maple, ash, and poplar for bodies, mahogany for necks, and ebony for fret boards. The choice of body material and shape of these guitars can have a significant impact on the timbre of the completed instrument as well as on aesthetic considerations. Other design options include finishes, such as lacquer, wax and oil along with flat and carved designs. Bass guitar necks, which are longer than regular electric guitar necks, are generally made of maple.

A brief history

In the 1930s, inventor Paul Tutmarc from Seattle, Washington, developed a guitar style electric bass instrument that was fretted and designed to be held and played horizontally. Unfortunately, Tutmarc inventions never caught the public imagination, and little further development of the instrument took place until the 1950s.

In the 1950s, Leo Fender developed the first mass produced electric bass. In the 1950s and 1960s, the term Fender bass was widely used to describe the bass guitars, because of early popularity of Fender in the market for mass produced bass guitars.

Different components of the bass guitar

Thi skind of guitar uses various components to produce music. Some of these components are strings and its tuning, fret or fretless bass, pickups, amplification and effects.

Frets and fretless bass
Frets are a raised metal strips inserted into the fingerboard that extend across the full width of the neck. On a fretted bass, the frets divide the fingerboard into semitone divisions. The original Fender basses had 20 frets. Fretless basses have a distinct sound, because the absence of frets means that the strings must be pressed down directly onto the wood of the fingerboard.

Strings and tuning
The standard design for the bass guitar has four strings, tuned E, A, D and G, with the original frequency of the E string set at about 41 Hz, making the tuning of all four strings the same as that of the double bass. This tuning is also the same as the standard tuning on the lower four strings on a 6 string guitar, only an octave lower.

Pickups
Most electric basses use magnetic pickups. The vibrations of the instrument metal strings within the magnetic field of the permanent magnets in magnetic pickups produce small variations in the magnetic flux threading the coils of the pickups.

Amplification and effects
The electric bass is always connected to an amplifier for live performances. Electric bass guitarists use either a combo amplifier, which combines an amplifier and a speaker in a single cabinet, or an amplifier and a separate speaker cabinet.

The electric guitar can be played either solo or with other instruments. It has been used in numerous genres of popular music, as well as classical music.

Different types of electric guitars

There are various types of this popular instrument available in the market. While shopping for an electric guitar for one’s personal use, the decision should be carefully taken about which one will be the right choice and make. The types include:

Solid body
These guitars have holes for neither sound nor an internal cavity to accommodate vibration, such as those used to amplify string vibrations in acoustic guitars. They are generally made of hardwood with a lacquer coating and have 6 steel strings.

Hollow body
These guitars have a hollow body and electronic pickups mounted on its body. The hollow body vibrates and the pickups convert a combination of string and body vibration into an electrical signal.

Electric-acoustic
In these guitars the pickups do not produce a signal directly from the vibration of the strings, but rather from the vibration of the guitar top or body. So,these are also called acoustic guitars.

Seven-string
Seven string electric guitars were popularized in the 1980s.

Eight string
Eight string guitars are rare, but not unused.

Twelve string
Twelve string instruments feature six pairs of strings, usually with each pair tuned to the same note.

Apart from these there are few other types of these popular makes available in the market which are bought according to their requirement.

Selecting the right kind of electric guitar

The primary reason for buying a guitar will be playing it. But one would also look for something whose resale value will increase in time. Craftsmanship is an important element in the future value of this instrument.

Areas that require special skills, such as binding, finishing, hand shaping and inlaid work, are forever expensive and will enhance the value of guitars in the future.

Thus things to look for while buying an electric guitar will be

Good Tone Wood
Although the sound of a good guitar would seem to come entirely from the pickup, the type of wood has an important influence on tone and sustenance.

Noise free instrument
The pickups on guitars and basses should be shielded from extraneous electronic sources that can cause humming and buzzing. And they should be covered in wax or epoxy to prevent micro phonic feedback.

Checking out the Neck Joint
The neck joint should be tight and rigid so that none of the string vibration is transferred to the neck.

Testing the sustenance
An electric guitar with greater rigidity and weight, such as a solid body, will sustain longer than one with less rigidity, such as a hollow body.

Checking out the bridge
The bridge maintains intonation and action of string height. Adjusting the truss rod or changing string gauge can change intonation or action.

The Truss rod
An adjustable truss rod can correct any changes in neck curvature.

These are the basic and most important factors to be considered. But, there are various other factors to be considered while shopping for an electric version. And while buying one should remember that a good guitar is for a lifetime.

During the era of big band, an instrument was necessary who can compete with the large volume instruments used in the jazz concerts of 30s and 40s.And that is why electric guitars were invented.

Electric guitars have a very interesting history. The string instrument makers, people who are enthusiastic about electronics and instrument manufacturers have designed it. They designed it in different combinations.

The pre historic guitar had a twang sound. Then the quest for a different sound began that led to the birth of an electric guitar, which had an amplifying horn in mid 20’s of the last century. During 1920 and 24, Lloyd Loar invented the first pick up. In 1936, mass production of electric Spanish guitar (ES 150) begun. Jazz musician Charlie Christian used to play this guitar. In the year 1943, Leo Fender created a solid body electric guitar with oak wood

In the 1950s, different kinds of electric guitars like Explorer, Flying v were invented. After these inventions, electric guitars started to fly higher. Many famous musicians, like Bob Dylan, Jimmy Hendrix, BB King, Chuck berry popularized the electric guitars.

Bands like Guns and Roses, Europe, Queen, Deep purple also popularized this instrument.

Electric guitars are very different from that of other string instruments. This is one string instrument where you can play both the lead and the rhythm portion. This is actually a type of instrument where the vibration that comes from its strings converts into electrical current. And it is being amplified, that gives a metallic tone to them.

The tones of electric guitars can be changed. To do this, you need a gazette called processor. This processor offers you different kinds of tones. You can mix two or more tones or create some of your own tones with the help of the processor. There are several other tricks also, that can be done by the electric guitar. Like, distortion, tremolo etc.

This instrument was basically associated with rock music. But as time moved on it tied its knot with several other kind of music like jazz, blues, country music, rock n roll etc. It can be said that electric guitar has become an indispensable part of the 20th century music.

The first performance with an electric guitar was during the year 1932 in Wichita, Kansas. George Barnes was the first person to use an electric guitar in recording. He was the one who recorded two songs in Chicago on 1st March, in the year 1938.

In today’s music scenario, electric guitars are gaining more and more importance. Today, we cannot imagine a music show without them. As the instrument got popular, the players also started getting noticed by the public. Even now they are so popular that we first notice the guitar player than any other musician in a music show. Electric guitars are no more under dogs, but it can be said that they are now ruling the instrumental world.

Besides the above mentioned point, one more fact should That should be pointed out here is that good guitar care not only increases the durability but also adds to the playability and longevity of the instrument. This holds true for all kinds of guitars, be it acoustic, electric or classical. Therefore, a good guitarist should have a clear knowledge about the maintenance and care of his instrument.

The story of guitar care starts with the storage. The musician can be a frequent player, or a performer, a teacher, or can be a rare user. But in every case, the common necessity is the good storage system of the instrument, which will protect the guitar from any kind of physical damage. For this the guitar needs a well fitted guitar case. Keeping it in a case will prevent it from various kinds of damages like scratching, mistreatment, accidental hitting, stepping etc. Other than this, a case will be a good safeguard while traveling with the guitar as it will prevent the instrument from heat and direct sunlight, which basically makes the wood dry, cracked and brittle.

Next with it comes the storing of the guitar. The perfect or the suitable temperature to keep the instrument is the room temperature (i.e. between 55-65 degrees Fahrenheit). This will save it from the effects of the climatic changes. Even using a humidifying system helps keeping the instrument safe.

Switching over to the next procedure of guitar care, it is the cleaning. Definitely it should be cleaned everyday and of course after every use. First of all, a soft cotton cloth should be used for cleaning as well polishing the guitar. Coming to the cleaning of the strings, it is a must to wipe them after each use as it will lengthen the tonal life of the strings.

In case of fingerprints, stains or any other kind of dirt on the body of the guitar, huff some breath on the surface and follow it with wipe. This will remove them. If more powerful cleaning is needed, the cloth can be moistened with little bit of water mixed with mild detergent. There are lots of guitar polishes and cleaners available in the market, which can be used for guitar care.

An old guitar needs much more care than the new one. To remove the stickiness, the solvent of mineral spirit or naphtha can be used with the help of a disposable cloth. To clean the fingerboard especially, lemon oil or any other oily cleaner can be used. But it should be kept in mind that too much of oiling and scrubbing may damage the instrument.

Adding to the guitar care process one of the important things is changing the guitar strings. When the strings start sounding dull, it is time to change. Of course it depends on how often the guitar is played. Generally the time to change the strings is after every 1-3 months.

Following the history of guitars the modern guitar comes from the Roman cithara brought by the Romans to Hispania around 40 AD. They further modified and developed it with the entrance of the four string oud, brought by the Moors. In other parts of Europe, the native six strings Scandinavian lut (lute) had gained in reputation in areas of Viking incursions across the continent.

The composers for the string instruments wrote mostly in tablature notation. During the 17th century, Italy was said to be the capital of the guitar world. In France, the guitar was considered to be the instrument of the nobility. The Spanish school of guitar creation flourished after the end of the eighteenth century. The works and composition of the composers traveled widely including the Italians composers who were involved in a number of substantial works.

One of the most vital factors in the history of guitars was the addition of the sixth string during the middle of the eighteenth century. The changes in social conditions and improvement in the mode of transportation during the 19th Century contributed to the growing understanding of the guitar and enabled performers to travel with their composition. Guitar music thrived Spain more than others in the 19th century.

The early 20th century saw the European emigrants coming to America brought a number of highly skilled instrument makers among them, including those who were expert in the manufacturing of steel stringed acoustic guitar. Two types of construction evolved, the flat top guitar and the arch top guitar. Martin and Gibson were two of the original and most significant of all American acoustic guitar makers.

A well recognized name in the history of guitars, Antonio Torres Jurado (1817 to1892), developed the modern feature of the guitar in Seville during the 1850s. George Beauchamp in 1936 patented the electric guitar, which used the horseshoe magnet pickup. However, Danelectro was the first to produce electric guitars for the wider public.

The requirement for something with an amplified sound became noticeable during the big band era of history of guitars. Amplified devices became necessary in order to fight with the loud volumes of the large brass sections common to jazz orchestras of the thirties and forties. To begin with the component of electric guitar, this consisted primarily of hollow archtop acoustic guitar bodies to which electromagnetic transducers had been fixed.

The original recognized use of the electric guitar in the history of guitars was during October 1932 in Wichita, Kansas by guitarist and bandleader Gage Brewer who acquired two instruments directly from George Beauchamp of Los Angeles, California. The first recording of an electric guitar was by jazz guitarist George Barnes. He recorded two songs in Chicago on March 1st, 1938. These were Sweetheart Land and It is a Low Down Dirty Shame.

Discussing about how to tune a guitar, the first point to be mentioned is the perfect meaning of tuning. Normally a guitar has six strings, each of which is of different size and posses different note value. Tuning a guitar means adjusting the pitch of each of these strings so that they play the correct note. This basically is done by tightening and loosening each of the tuning pegs (as tightening raises the pitch of the strings and loosening lowers it).

Talking about, how to tune a guitar, the next point follows is the type of tuning. Mainly the process that is followed to tune a six-string guitar is the standard tuning. The pattern of the strings is like this:

- E is the 6th string and the lowest sounding one.
- A is the 5th string.
- D is the 4th string.
- G is the 3rd string.
- B is the 2nd string.
- E’ is the 1st one and the highest sounding string.

Other than standard tuning, the guitar tuning option also includes alternate guitar tuning. The guitar can be tuned to Drop D, Open C, Open G, , Open E or Admiral, Half step down, and Full step down. But the most popular one for both Electric and Acoustic guitar is the standard tuning and a perfect answer to the question how to tune a guitar.

However, it should be noted that in a perfect tune, the 1st and the 6th strings open must produce the same note, of course at different pitches. Therefore, following the standard tuning, lets see how to tune a guitar methodically:

E String Tuning – To tune the sixth string, the tuning peg has to be slowly adjusted after playing the pitch. And it is necessary to tune up by increasing the string tension. Until and unless the sixth string is tuned to E, the other strings cannot be tuned.

A String Tuning – To tune the fifth string, the first thing to be done is to placing the index finger of the left hand just behind the 5th fret of the 6th string and slowly playing the 6th string at the 5th fret with the right hand. Next is to adjust the 5th string tuning peg gently until both the notes are same.

D string tuning – Same as the last one, the tuning of the 3rd string can be done by putting the first finger of the left hand behind the 5th fret on the A string, which is the D note. Then gently tuning the 4th string i.e. the D note to the last one is the only thing to follow.

G string Tuning – Just like the last one, the tuning of the G – string needs placing the first finger of the left hand behind the 5th fret on the D string, which is the G note. Then a gentle tuning of the G-string to that note is all to be done.

B String Tuning – The tuning needs the first finger of the left hand to be placed behind the 4th fret and the rest is same as the earlier one, i.e. to adjust to the last one.

E’ String Tuning – The tuning needs the first finger of the left hand to be placed behind the 5th fret on the B String, which is the E’note. Rest is to adjust E string to that of the last string.

Now that you have learnt how to tune a guitar, get tuning.
