The Difference Between Acoustic and Electric Guitar

The differences between acoustic and electric guitars are myriad. In addition to one requiring electricity to be heard and the other one not requiring anything but a skilled set of hands, the way in which each one is made and the uses of each one stand in stark contrast to one another.

An acoustic guitar is a hollow-bodied, six-stringed instrument. The sound produced by an acoustic guitar comes from the vibrations created by a note or notes being plucked or strummed on the strings and echoing throughout the hollow inside of the instrument’s body. Steel-stringed acoustic guitars are made of wood, and the tops of acoustic guitars are usually made from spruce, although some are made from rosewood or maple. Other acoustic guitars are nylon-stringed, or classical, guitars. These are usually smaller, and the strings are tied to the bridge in a knot rather than held in with a peg like on steel-stringed acoustic bridges. Classical guitars are used in a variety of musical applications from jazz, traditional Latin folk music, to, of course, classical guitar compositions. Classical guitars are most often played with the fingers, but a plectrum may be used to play either steel-stringed or classical acoustic guitars. Blues, rock, and most Western folk music is played on steel-stringed acoustic guitars. While acoustics are traditionally played without the need for electric amplification, acoustic-electric models–acoustic guitars equipped with electric pickups–are quite popular for acoustic artists whose professional needs call for amplification.

Electric guitars, on the other hand, can be hollow-bodied or solid. In the twenty-first century, hollow-bodied electric guitars are less commonly-used than solid-body variations, but a number of rock, blues, and jazz musicians still prefer the tones they produce. Hollow-bodied electric guitars usually have f-holes (like a violin or cello) as opposed to the single, large, circular hole in an acoustic guitar body. The first solid-body electric guitar, the famous Les Paul model, was introduced in the 1950s, and since then the solid-body electric guitar has become a staple for guitarists involved in all genres of popular music. Solid-body electrics feature either a bolt-on neck (like the Fender Stratocaster) or a set-in neck (the Les Paul, for example), and can make use of either single-coil pickups for use with clean channel amplification or humbucker pickups for use with distortion. Electric guitars, unlike acoustics, are rarely manufactured with natural finishes. The bodies can be made from a number of different woods, but the most common are alder, ash, or mahogany. The mahogany bodies of most Gibson guitars are credited for the warm tones their guitars produce. There are, however, a limited number of electric guitars that make use of synthetic materials since all the guitar requires to be heard is amplification as opposed to a hollow cage of wood. Even so, the most popular electric guitars are made from wood and are believed to provide superior tonality than those made from anything else.

The Golden Gate Bridge

The Golden Gate Bridge in San Francisco is a marvelous feat of Engineering. Located on the Golden Gate Strait in San Francisco Bay, the idea of a bridge linking the two sides of the bay was first discussed in 1872. It wasn’t until the 1930`s that an Engineer named Joseph B. Strauss submitted the final plans for the bridge to the District Board of Directors and construction began.

The Art Deco styling that the bridge is famous for was the idea of the husband and wife partnership, Irving and Gertrude Morrow, with their subtle ideas and eye for good taste; they created the easy on the eye bridge span. With opposition from the US Navy, Morrow and his wife chose a unique colour for the bridge known as ‘International Orange’ and this has become famous all over the world. As Chief Engineer Strauss was very safety conscious he, with the help of Edward Bullard, a local manufacturer of safety equipment, introduced new, ground breaking safety procedures which are still followed on a high percentage of construction sites to this very day. The death rate for men working on the bridge for the time of construction was second to none showing how important safety precautions where and still are.

Wheel – Oldest and Remarkable Invention of Man

I’ve been thinking of some possible reason on how this civilization came up to this state of technological dependency? What was the past generations’ contribution to this effect? I read books, journals, and many other source of information including the net just to find a simple clue for this. Only one thing I have observed from those records, man never stop in finding solutions how to make life smooth and easy. They invented things, conducted studies and framed theories. And one of their remarkable inventions was the wheel.

The wheel is a big help in our lives. Using carts in simple transportation of goods from one place to another, up to the exploration of oceans and galaxies. This equipment was developed and used as component of complicated machines which enables us to work with speed and accuracy. This was also used by great men and women in the history of kingdoms and empires. Wheel was attached to their armaments, catapults, and chariots for their advantage in conquering lands, and protecting territories from invaders. This invention helped in the progress of the world’s economy, industry, and technology.

The construction and transportation industry will never move forward without the wheel. The construction of high rise commercial and residential buildings, lengthy expressways, bridges, flyovers, and in the excavation of subways and tunnels, wheel is undeniably present. Through the expertise of the operator, the heavy equipments used in these projects safely moves because of the wheel. In transporting agricultural and industrial products, from the rough carts of cave people up to the automobiles of this modern civilization, wheel is always a component. Some are simple in design others are artistically manufactured to enhance beauty and elegance. Scientists, researchers, and inventors don’t stop in developing this thing in order to utilize its full function with convenience and efficacy.

Wheel is also useful for kids in parks and playgrounds. It enables children to interact each other that they could develop good physical built and a wholesome character. it delivers laughter in amusement centers and casinos, sports enthusiasts gain fame and wealth, hobbyists such as a potter finds satisfaction and relief, and house chores over and done with comfort. Our disabled fellowmen who could not walk now can see the beauty of the surroundings.

All that I wrote above are the benefits accounted for the invention of wheel. Not to mention its worse effect when handled with negligence. But, as long as man seek out for easy way of life and search for industrial and technological advancement, wheel will always share a role in our existence.
