What You'll Learn
Electric music technology
The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878. The next major technical development was the invention of the gramophone disc in 1889. For much of the 20th century, records were the most common way of selling sound recordings. The widespread availability of records and the development of radio broadcasting enabled a larger number of people to listen to songs performed by top artists, leading to the development of national and international musical stars.
In the early 20th century, electric technologies such as electromagnetic pickups, amplifiers, and loudspeakers were used to develop new electric instruments. Examples include the electric piano (1929), electric guitar (1931), electro-mechanical Hammond organ (1934), and electric bass (1935). These electric instruments do not produce a sound audible to the performer or audience unless connected to amplifiers and loudspeakers.
The Moog synthesizer, invented in the 1960s, popularized analog synthesis. The 1980s saw a shift towards digital technology with the development of the Musical Instrument Digital Interface (MIDI) standard, allowing electronic instruments to communicate with computers and each other. Digital synthesizers, like the Yamaha DX7, became widely popular.
Today, electric music technology includes a wide range of devices and software used to make or perform music, such as computers, electronic effects units, and digital audio workstations. The study of music technology involves the creative use of technology for creating new sounds, performing, recording, programming sequencers, manipulating and mixing music, and more.

Electric sound recording
The introduction of electricity to the process of sound recording has had a profound impact on the music industry, transforming the way sound is captured, amplified, and reproduced. This evolution, known as the Electrical Era, revolutionised the recording process and paved the way for numerous innovations.
The earliest attempts at electrical recording date back to the 1920s, with the funeral service for The Unknown Warrior in Westminster Abbey, London, in 1920, being one of the first electrical recordings issued to the public. However, the audio quality was weak and unclear. It wasn't until the mid-1920s that electrical recording technology started to gain traction, with companies like Victor and Columbia adopting the Western Electric system. This technology utilised microphones, electronic amplifiers, and electromagnetic cutting styluses to create records with more realistic sound reproduction.
The use of microphones allowed for a more comfortable recording experience for musicians, eliminating the need to crowd around the recording horn. It also ushered in the age of the crooner, with softer voices now being favoured due to the improved sensitivity of microphones. Electronic amplification played a pivotal role in the development of broadcast radio, public address systems, and electronically amplified home record players. Additionally, the amplification of musical instruments enabled quieter instruments, such as the guitar and string bass, to be heard on par with louder wind and horn instruments.
The Western Electric system significantly improved the fidelity of sound recording, expanding the reproducible frequency range to between 60 Hz and 6000 Hz. This advancement allowed audio engineers to capture a fuller, richer, and more detailed sound using multiple microphones connected to multi-channel electronic amplifiers, compressors, filters, and mixers. The introduction of magnetic tape recording by the allied nations in 1945 marked another significant milestone in the evolution of electric sound recording.
The electro-acoustic transducer, commonly known as the loudspeaker, remains one of the most crucial and enduring inventions from the Electrical Era. This device converts electronic audio signals back into audible sound through a process known as transduction. Transduction involves converting sound waves into electrical signals, amplifying them, and then converting them back into mechanical energy that produces sound through a speaker. This process is fundamental to recording audio and amplifying sound, allowing music to transcend the acoustic boundaries of physical spaces.

Electrical signals in music
The electrical signals in music are made possible by the function of a microphone, which acts as a transducer. When a musical instrument is played, it produces sound waves that travel through the air and hit the microphone, causing the diaphragm inside it to vibrate. These vibrations are then converted into electrical signals through a process known as transduction. This process involves transforming air pressure fluctuations (sound waves) into electrical signals.
The electrical signal generated by the microphone is then amplified and transferred through wires to a speaker. At the speaker's end, another transduction process takes place, converting the electrical signals back into mechanical energy. This movement of the speaker cone recreates the original sound waves, amplified so that we can hear the music.
The advent of electrical waves and the ability to convert sound into electrical signals have revolutionized the music industry. Before electricity, the reach and impact of music were limited to the acoustic boundaries of physical spaces. Now, with the help of microphones, speakers, and amplifiers, music can be amplified, recorded, and distributed on a much larger scale.
Electric music technology refers to musical instruments and devices that use electrical circuits, often combined with mechanical technologies. Examples include the electric piano, electric guitar, Hammond organ, and electric bass. These instruments produce sound waves that are converted into electrical signals, which can then be amplified and converted back into sound by speakers.
The development of electronic music and synthesizers has also played a significant role in the evolution of electrical signals in music. Composers and musicians have explored the possibilities of electronic sound equipment, leading to the growth of synth-pop and the dominance of synthesizers in pop and rock music during the early 1980s. The definition of MIDI and digital audio has further facilitated the creation of purely electronic sounds.

Transduction in music
Sound is a type of longitudinal or compression wave that travels through a medium, such as air or water, by causing particles to oscillate back and forth. These oscillations create areas of high and low pressure, which our ears interpret as sound. When a musical instrument is played, it produces sound waves that propagate through the air and reach our ears.
In the context of transduction, these sound waves are captured by a microphone, which acts as a transducer. The sound waves vibrate a diaphragm inside the microphone, causing it to move back and forth. This movement generates an electrical current that corresponds to the characteristics of the original sound wave, including its frequency and amplitude.
The electrical signal created by the microphone can then be amplified and transferred through wires to a speaker. At the speaker, another transduction process occurs. The electrical signals are converted back into mechanical energy, causing the speaker cone to vibrate and recreate the original sound waves, but with amplification. This allows the sound to be heard at a higher volume.
The development of transduction and electrical waves has had a significant impact on the music industry. It has enabled the electrical conversion and amplification of sound, allowing music to be recorded, reproduced, and heard by larger audiences beyond the acoustic boundaries of physical spaces. Electric music technology includes musical instruments and recording devices that utilise electrical circuits, such as electric pianos, electric guitars, and speakers.
Additionally, the advent of electronic music has further expanded the possibilities of music creation. Composers and musicians now have a wide range of electronic sound equipment and synthesizers at their disposal, allowing for the exploration of new sounds and the dominance of electronic sounds in popular music.
