A primer on the history of the synthesizer in popular music

The story of the synthesizer in popular music is rarely a clean linear arc. It is more accurately a braided river of technological breakthroughs, eccentric inventors, opportunistic record producers, and musicians willing to sound unfashionable for a few years in pursuit of a sound no one had heard before. The instruments that once seemed like laboratory curiosities now sit at the centre of pop, hip-hop, R&B, and ambient music, and they are stocked in the same record shops where people still browse for acoustic folk LPs and noise cassettes. For collectors who keep an eye on experimental reissues, sites such as Broken-Music have become a useful place to trace how the gear, and the music made on it, has continued to evolve.

This primer walks through the main waves of synthesizer adoption, from the first Moog modular systems squeezed onto university campuses through to the Eurorack revival that has taken root in bedrooms and warehouses from Berlin to Brunswick. Along the way it touches on the records that defined each era, the cultural friction that accompanied every new sound, and the local scenes that absorbed and reinterpreted electronic instruments, including those in Australia, where a long tradition of independent electronic production runs alongside the country's rock and pub traditions.

Early pioneers and the birth of electronic sound

The earliest electronic musical instruments predate the synthesizer proper, but the lineage is clear. The Theremin, patented in 1928, demonstrated that pitch could be controlled without physical contact, and the ondes Martenot, the Trautonium, and the Hammond organ all extended the idea that electricity could be a viable sound source. The term "synthesizer" in its modern sense, however, usually points to the work of Robert Moog and Don Buchla in the mid-1960s, whose voltage-controlled instruments turned bulky laboratory equipment into something a musician could theoretically play. The Moog modular, demonstrated at events covered by the Audio Engineering Society, was famously temperamental, required patch cables for every parameter, and cost as much as a small car.

Pop music's relationship with these early machines was cautious. The Monkees' "Daily Nightly" in 1967 featured a Moog, and within a year Wendy Carlos's Switched-On Bach had moved the instrument from novelty to respectable, eventually selling more than a million copies and making the synthesizer bankable for crossover audiences. The Beatles' Abbey Road in 1969 included a Moog prominently, and George Harrison and John Lennon both used the instrument on solo work, signalling that the new gear had crossed from the avant-garde into the working pop musician's toolkit. In Australia, public broadcasters began to take notice, and listeners to the ABC's late-night programming could occasionally hear pieces that mixed orchestral and electronic textures, even if the equipment was still rare in the country's music shops.

The 1970s: synthesis goes mainstream

The 1970s saw synthesis stop being exotic and start being structural. Kraftwerk in Germany built entire records around custom rigs, and their influence rippled through disco, prog, and the emerging European electronic underground. Pink Floyd used the VCS3 and the Minimoog across Dark Side of the Moon, giving synthesizers a place in stadium rock that was previously reserved for guitar solos. Stevie Wonder's run of records in the early part of the decade, from Music of My Mind through Songs in the Key of Life, showed that synthesis could be soulful rather than clinical, and that an R&B audience would follow the gear anywhere as long as the songs held up.

The decade also brought the first affordable instruments. The Minimoog, released in 1970, was portable enough to be taken to a gig. The ARP Odyssey, the Korg MS-20, and the Sequential Circuits Prophet-5, the first fully programmable polyphonics, all arrived before 1980, and each one lowered the barrier between bedroom and bandstand. In Australia, Countdown on ABC TV regularly featured homegrown acts, and bands such as Skyhooks and the Canberran project Tully were already exploring synth textures, even if the country's pub-rock scene was still dominated by guitars. Australian audiences first heard the Prophet-5 on records by international touring artists and a handful of local producers who managed to import the gear, often at a price in Australian dollars that would make today's collectors wince.

Synthpop and the 1980s

The 1980s were the decade the synthesizer became shorthand for modernity. Depeche Mode, the Human League, Soft Cell, OMD, New Order, and countless others built entire identities around drum machines and polyphonic synths. The Yamaha DX7, released in 1983, was the first digital mass-market synthesizer, and its bright, glassy electric piano sound appeared on practically every pop record of the mid-1980s, including Michael Jackson's Thriller, Brian Eno's Apollo soundtrack work, and a long list of Australian releases. INXS, Icehouse, Pseudo Echo, and the early models of synthpop acts from Melbourne and Sydney all sat comfortably with the global sound, and the country's Triple J station began to play electronic music more systematically, especially after the launch of its Unearthed platform in the 1990s, which would later become a launchpad for homegrown electronic producers.

The synthpop era also entrenched the idea of the electronic record as a designed object. Album sleeves were austere, typography was strict, and singles often came in multiple 12-inch formats with extended mixes. Local record shops in suburbs like Sydney's Newtown and Melbourne's Brunswick developed reputations for stocking imports and small-run releases that the bigger chains ignored, and the secondary market for vintage analog gear began to harden. A clean Prophet-5 in original packaging was, and remains, a serious investment, and the Australian dollar price for serviced vintage units has only climbed as the supply of working examples has dwindled. A few operators, including the dedicated store at the centre of this piece, have built businesses around tracking down exactly these kinds of instruments and the records that celebrate them, with releases such as Late Monoliths sitting comfortably alongside established reissue lines.

Digital, sampling, and the 1990s to 2000s

The 1990s moved the centre of gravity from analog to digital. The Roland TB-303, originally a failed bass-line accompaniment from 1981, became the foundation of acid house after a generation of Chicago and Detroit producers discovered it second-hand. Sampling, made famous by the Fairlight CMI and the Akai S1000, allowed producers to incorporate any sound they could record, and the result was a generation of records built on sonic collage. Autechre, Aphex Twin, Squarepusher, and the entire Warp Records roster pushed the digital instrument into genuinely experimental terrain, while producers in the American R&B and hip-hop mainstream used samplers to make hits that were as much about memory and reference as they were about melody.

Australia's electronic scene during this period was small in commercial terms but unusually adventurous. Melbourne in particular nurtured labels and clubs that ran parallel to what was happening in Detroit and Berlin, with a strong crossover between indie rock and electronic production. The Avalanches, Cut Copy, the Presets, and Midnight Juggernauts all emerged from this period, and the country's festival circuit, from Meredith to the Big Day Out, began to book electronic acts alongside guitar bands as a matter of course. A niche market for vintage analog gear coexisted with an emerging interest in boutique modular systems, and the local DIY ethos, summed up in the casual Australian phrase "she'll be right" even when things clearly weren't, encouraged producers to build their own gear and share schematics.

The hardware renaissance and contemporary currents

The 2010s and 2020s have been marked by a quiet but stubborn return to hardware. The Eurorack modular format, which standardises the physical and electrical characteristics of small synthesizer modules, has spawned an industry of small builders, and a generation of musicians has rediscovered the tactile immediacy of patching a cable from one oscillator to another. Affordable reissues of classic instruments from Korg, Roland, and Behringer have put analog polyphonics within reach of working musicians again, while software instruments from makers such as Native Instruments and Arturia have continued to improve. The result is a musical landscape in which the boundary between hardware and software is increasingly porous, and in which the synthesist might easily be playing a Eurorack system at a gallery opening and a laptop at a festival the same week.

In Australia, this era has produced its own scenes. Brisbane's small but persistent modular community, Melbourne's storied nightclub culture, and Sydney's Vivid festival, with its heavy emphasis on audiovisual and electronic work, all provide platforms for new electronic music. Musicians who learned on free software and YouTube tutorials now collaborate with players who have decades of analog experience, and the cross-pollination has produced hybrid performances that are neither purely vintage nor purely digital. For listeners who want to explore this lineage, the records that document it are easier to find than ever, and even those who came to electronic music through a different instrument sometimes find themselves browsing for vintage oscillators and even picking up a second-hand electric alongside their modular setup, which is why a side trip to suppliers such as acoustic guitar supply is not as out of place as it might seem.

The thread that runs through this whole history is that synthesizers have rarely stayed still for long. Each generation of instruments has produced music that the previous generation would not have recognised, and each has eventually been reabsorbed into the broader pop mainstream. The records made on these machines, from the early Moog experiments through the DX7 pop crossover, the 1990s digital underground, and today's modular renaissance, are still being reissued, remastered, and listened to, and they continue to shape what musicians do next. The instruments themselves, from vintage analog units to brand-new Eurorack modules, remain the most concrete evidence of a story that is still being written, and the best way to understand where the synthesizer is going is to spend some time with where it has been.
