To help really understand just how advance music technology has become a slight history. William Duddell, a physicist, in 1899 was commissioned to find a way to stop the annoying whistling sound made by the electric streetlights. He built a machine named the Singing Arc to use during it lectures. He had a keyboard, which he was able to control the oscillations in the circuit. He was even able to play tunes on this amazing creation! By 1902 the first synthesizer what introduced by Thaddeus Cahill. He invented a contraction called the Telharmonium. It was designed to broadcast music over the New York telephone system. Unfortunately it created so much commotion and chaos that it was dumped into the Atlantic Ocean. Electronic sound production also was over as fast at it had started. Orchestral composers Richard Strauss and Berlioz who have orchestral scores that called for a remarkable amount of instruments and also usually needed unusual percussion effects. Another composer later on named Varese carried the technology further. He fully believed in the use of electronic sound producing instruments and believed that music should be representative of the machine age. Varese believed that music generated by electronic devices should be capable of producing sounds consistent with those of modern life and he was right. In the 1920’s music technology really took off. The first commercial instruments were intended for Music Hall and Variety rather than the classical world of music. The main instruments that appeared were the Theremin (most well known for its appearance in the Beach Boys' Good Vibrations), the Ondes Martineau (which appears in several compositions by Olivier Messiean) and an electronic organ invented by Laurens Hammond. The Theremin is responsible for making wailing sounds in early films especially science fiction and is made its unusual sounds with out the player ever touching it. A composer by the name of Karlheinz Stockhausen used a device called the Hammond organ in some of his early electronic compositions. "In the period leading up to the Second World War electronic instruments were becoming firmly established in the popular and art music fields and they were being used a great deal in films and radio. Records were being used not only to store sounds but also to manipulate sounds. "
John Cage's Imaginary Landscape No. 1 (1939) made the performers to have to place the stylus on and off the record in order to manipulate sounds previously recorded. This technique was and is still favorable with artists in the late 1980s and 1990s. During the 1930s advances were made in recording technology using magnetic tape which was an early rendition of reel to reel recording. And the development of inventions such as the electric guitar and amplifiers.

Different parts

There are actually different types of recording styles. Most fit into two categories; monaural (mono) and stereophonic (stereo) and then within those two categories are subcategories. The subcategories for monaural recording are binaural and multichannel while stereophonic recording’s subcategory is multitrack. Monaural recordings are the first type of recordings ever used. They consist of a single channel of audio and the depth is apparent by how much ambient sound is present with the track is recorded. Ambient sound is the surrounding and encircling sound produced. Monaural recording is normally used for audio new footage, dialogue recordings for radio, video and film, sound effects, radio dramas and audio books. Stereophonic recordings consist of two audio channels (like Binaural) but "the depth and space in the recording is determined by the amount of ambient sound in the recording (similar to Mono)." Stewart. Stereo is most frequently used recording technique and if the one most used in commercial recordings. Stereo recording are mostly used in commercial recording (like pop music and such), music for videos and film, audio books, sound effects, and radio dramas.

Two categories in the monaural category are Binaural and Multi-Channel. Binaural recording are consisted of two audio channels. The two channels are recorded by placing two microphones about 6.5 to 8.5 inches apart that’s about the width between the human ears. A baffle (a partition that prevents interference between sound waves in a loudspeaker) is placed between the microphones. It approximates the effect of the human head has on what the sound is like when it reaches the human head. When this kind of recording is used when you listen to it with headphones on you hear really deep sound with a three dimensional sound field and this kind of recording actually can make you feel like your listening to it from the original surroundings it was recorded in. But of course there is always a downfall to something good. With Binaural recordings the three-dimensional sound can only be heard with headphones because with loud speakers the sound field is lost and the Left/Center/Right relationships gets overstressed and losses the dimension it once had. Multi-channel recording are used today for many purposes. Depending on the produces vision of how they should be intended to be heard they could be consisted of anywhere from 3 to 18 or even more channels. Hence the name multi-channel. Multi-channel recordings are characteristically written to discrete tracks or actually sometimes encoded into one data stream that then gets decoded just proceeding to the playback. Typical multi-channel sound is delivered by methods such as Dolby Surround, Dolby AC3, Dolby 5.1, THX, Quadraphonic, and Ambisonics. The pro’s and con’s of this style is that "the sound designer and producer can get extremely creative with the music score, the sound effects and even the dialog as far as where to place it in the sound space. For example with a 15-channel delivery system you can have 360 degrees of sound coming from 15 discreet channels. The disadvantages to multi-channel sound is that it can be expensive and complicated for a consumer to listen to the material at home as it usually requires higher end equipment than a traditional home entertainment center, however there are standards out there such as Dolby 5.1 and THX that help to ensure that home users can approximate what the sound designer was intending for them to hear. One other trait of multi-channel recordings that can be either an advantage or a disadvantage (depending on the producer's goals) is that they usually sound much larger than life, making them exciting to listen to, but often not as accurate as Stereo or Binaural sound. This isn't necessarily the fault of the recording itself, but more the playback method as when you have more than two speakers in a small room, they create effects that can change the level of realism drastically." Multi-channel recordings are mostly used for music and sound effects for video or film, sound effects/Foley, and commercial music releases.
