Guitars are in the family of stringed instruments. They typically have 6 strings but can have up to 20. These instruments vary in size, shape, and material. Guitars can be round, rectangular, and even circular. Guitar finishes can even be matte or glossy. Under the broad category of guitars, there are acoustic, electric, and bass guitars. In the 21st century, the majority of guitars are made of oak wood. Traditional wood guitars have nylon, brass, silver, or nickel strings. Nylon is acceptable for beginners but the other types of strings are harsh on finger tips. Convention guitars cause finger blisters, sore hands, and finger bleeds. Strings cost about 10 dollars a pack depending on how many one may need. Conventional wood guitars must be re-stringed every 2 months to prevent oil and dirt build up from causing a string to snap. Wooden guitars swell if not placed in the correct weather conditions. Guitars in the trunks of cars on a hot day, warp. When the wood warps, it ultimately changes the overall tone, quality, and reliability of the instrument. Guitar cases are highly needed to avoid that. Guitars accompany many styles of music such as smooth jazz, rock, and pop. The genres differ but all demand skill and accessories to be played. A typical guitar accessory is a guitar tuner, cables, straps, picks, and pedals. Cables allow guitars to be amplified. Straps enable guitarists to play guitar standing up. Guitar picks are rectangular bits of plastic that enable guitarists to pluck strings without hurting their fingers. Pedals are a tool guitarists use to create many different sounds such as reverb or whammy. Unfortunately, as of 2012 all oak wood trees vanished. Scientists and engineers are working on creating synthetic wood to continue production. Instead they came up with a better idea. Fast forward 50 years and we have a new generation of holographic guitars. In 2000, 1 in every 5 people purchased wood guitars. That number has significantly changed to 1 in every 500. Technology rules every aspect of life. Music engineers designed a guitar that can be easily accessed from smart phones. Holographic guitars are not bulky, do not require extra accessories, or skill. Virtually anyone that likes music can play this new guitar. Besides crisp string sounds and energetic rock, this guitar has different functions. One can access beat loops and synth pads. It is also possible to record, create and share music at the touch of a button. Holographic guitars allow people to convey a variety of moods and emotions. Regardless of the materials a guitar is made of, it is an instrument. A physical or virtual guitar all have the same thing in common, sound and imagination.
