A synthesizer is an electronic musical instrument that generate different types of sound, ranging from electronic and sampled to mimicking traditional instruments. It typically generates waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis.

Early history
The origins can be traced back to the early 20th century. One of the first electronic instruments was the Telharmonium, developed by Thaddeus Cahill in 1897. It used electromechanical technology to generate sound but was impractical for widespread use due to its size and complexity.
In the 1930s, the RCA Mark II Sound Synthesizer became the first programmable model, allowing composers to create music using punch cards. This instrument was used for experimental music, but it was still limited to specialised settings.
The advent of modular synthesizers
The 1960s saw the development of modular synthesizers, which allowed musicians to combine different components to create customized sounds. Pioneers like Robert Moog and Don Buchla introduced their own designs, making them more accessible to musicians. Moog’s models gained popularity with artists such as Wendy Carlos, whose album “Switched-On Bach” (1968) showcased the instrument’s capabilities and helped bring it into mainstream music.
Polyphonic synthesizer and digital revolution
The late 1970s and 1980s marked a significant shift with the introduction of polyphonic models, allowing multiple notes to be played simultaneously. The Yamaha DX7, released in 1983, was one of the first commercially successful digital models, utilizing FM synthesis to create complex sounds. This model became a staple in pop and rock music, influencing the sound of the era.
Modern use and software
Today, synthesizers come in various forms, from hardware units to software plugins. Digital audio workstations (DAWs) allow musicians to incorporate them into their compositions easily. The versatility of synthesizers has led to their continued relevance in contemporary music, with genres like electronic dance music (EDM) and hip-hop heavily relying on synthesizer sounds.
The synthesizer has evolved significantly since its inception, shaping the landscape of modern music. From its early beginnings to today’s digital era, it continues to inspire musicians and innovate sound creation.
