Have you ever wondered how something as complicated as a song can be perfectly recorded onto the surface of a flat, round disk of vinyl, that can be reproduced on mass for anyone to own, play and listen to whenever they choose?
Having access to music whenever and wherever you want is something many of us take for granted but have you ever imagined what it was like before this was possible? Before we had discovered a way to record and playback sound the only way to hear music was to have someone play it, or play it oneself. Imagine what a massive conceptual shift recorded music would had been for people once they were able to hear music, at will, without someone performing it in their presence for the first time. To fully understand the genius behind vinyl you first need to know the origins and history of recording and reproducing sound.
The history of recording and reproducing sound is a period spanning over a century. In 1877 Thomas Edison invented a device that could record and reproduce sound for the first time, not on a disc but a metal cylinder. The term ‘gramophone’ was coined by Emile Berliner whose system played lateral-cut disc records the were first marketed in Europe in 1889. The golden age for vinyl records as we know them was from the inception of the vinyl LP in 1948 to 1988 when CDs out sold vinyl for the first time, but vinyl had its first taste of competition from the Phillip’s Cassette, when it was released in 1962.
After decades of music seemingly disappearing into a computer hard drive, january 2017 saw Vinyl sales topping three million, the highest UK total in 25 years. More than 3.2 million records were sold in 2016, a rise of 53% on the previous year. If you are someone who considers themselves passionate about music, vinyl remains the singular most impressive format of recording and reproducing music. So it's only right we honour the vinyl record by fully understanding the genius behind it.
To understand the genius behind vinyl you first need to understand how sound waves work. Sounds are produced by vibrations and travel through the air as waves, which are vibrating particles. The waves transfer energy from the source of the sound out to its surroundings. Your ear detects sound waves when vibrating air particles cause your eardrum to vibrate. The bigger the vibrations the louder the sound. The groves you can see on a vinyl record are actually sound waves or more like a type of fingerprint of the sound waves captured in a lacquer disc that we call a vinyl record. These three-dimensional grooves cut in the vinyl record are a recording of how the sound waves behave as they move through the air.
A typical record player has a type of needle called a stylus that is placed gently on the vinyl record resting in the beginning of one of the groves. As the vinyl disc steadily rotates the stylus moves through the wavy three dimensional groves. The stylus is a tiny crystal of sapphire or diamond mounted at the very end of a lightweight metal bar like a needle. As the crystal vibrates in the groove, its microscopic bounces are transmitted down the bar. The stylus fits onto the end of an electromagnetic device called a cartridge, containing a piezoelectric crystal. The metal bar presses against the crystal and each time it moves, it wobbles the crystal slightly, generating an electrical signal. These signals are fed out to the amplifier to make the sounds you hear through your speakers or headphones. Not all record-player cartridges use piezoelectricity to convert sound vibrations to electrical signals. Some have tiny electrical coils and a magnet inside them. When the stylus moves, it pushes the magnet up and down past the coil, generating electrical signals that are fed to the amplifier to create sound through your speakers.
Many record collectors and DJ’s say the sound of vinyl is far superior and much "warmer" than digital music and this is why vinyl has always been the first choice for any music connoisseur. The revival of vinyl is testament to its superiority over all over music formats as it continues to remain the singular most impressive format for recording and reproducing music. Its difficult to imagine when or how vinyl could ever be replaced by a new music format claiming to do it better!
