Prologue: When the needle and the beat ruled
Text: mmr｜Theme: The history of the evolution of DJ culture, where the physicality of analog and the efficiency of digital intersect, redefining the meaning of the act of selecting music.
DJ culture is a culture born from extremely physical constraints. Born in the Bronx, New York in the 1970s, hip-hop was established as a practice of reconstructing existing music. DJs like Grandmaster Flash were at the center of this.
Using two turntables and a mixer, they extended the groove for the dancers by looping certain breaks on the record. The important thing here is that this operation was completely manual. Matching the tempo required the use of ears and fingertips, and any discrepancies had an immediate effect on the floor.
また、レコードは単なる音源ではなく、文化資本でもあった。どのレコードを持っているか、どの盤のどの部分を知っているかがDJの個性を規定した。レコードショップやディストリビューターとの関係も重要であり、情報と物理的流通が密接に絡み合っていた。
DJs of this era were not ““people who reproduced sound,” but ““people who cut out time and reconstructed it.” Music began to be treated as editable material rather than something that flowed linearly.
制約の中で磨かれた身体性が、DJ文化の基礎を形成した
アナログ技術の成熟とクラブ文化の拡張
From the 1980s to the early 1990s, DJ technology and club culture rapidly developed. With the birth of house and techno in Chicago and Detroit, DJs changed from being mere promoters of parties to being able to determine the direction of music.
During this period, turntable technology was further refined and advanced techniques such as scratching, transformers, and juggling were established. These were developed in the context of hip-hop, but also influenced club music.
At the same time, the club space itself evolved. Elements such as large sound systems, lighting and long sets are integrated, and the DJ becomes responsible for building the narrative throughout the night.
At this stage, analog music was still the mainstream, and there were physical constraints such as the weight of records and the cost of transporting them. However, these factors also encouraged careful selection of songs and made the DJ’s style stand out.
Restrictions were an inconvenience, but at the same time they were a device for creating style.
The advent of CDJs: the first wave of digitalization
In the late 1990s, DJ culture underwent its first major digital transformation. The CDJ, developed by Pioneer DJ, is a piece of equipment that aims to reproduce the feel of a turntable while using digital media called CDs.
The appearance of the CDJ-1000 was symbolic, allowing operations that were difficult to achieve with analogue devices, such as scratching with the jog wheel, setting cue points, and looping functions. This allows DJs to play with greater precision and repeatability.
また、CDという媒体はレコードに比べて軽量であり、運搬性に優れていた。これにより、DJはより多くの楽曲を持ち運ぶことができるようになり、セットの自由度が拡大した。
On the other hand, there were also criticisms regarding the sound quality and operation feel, and not all DJs made the switch immediately. However, as CDJs became standardized as club equipment, their widespread use became decisive.
Digital has gradually rewritten the standard in the field due to its convenience.
File-based DJ and software revolution
In the 2000s, music became more digital. With the spread of music files such as MP3, sound sources have begun to be completely separated from physical media. Symbolizing this change is the emergence of DJ software such as Serato DJ and Traktor.
These software integrate functions such as sound source management, waveform display, beat analysis, and effect processing, centralizing the DJ’s work. Of particular importance was the Digital Vinyl System (DVS), which made it possible to operate digital sound sources while using a traditional turntable.
Waveform displays introduced a visual element to the DJ’s work. Beat matching, which previously relied only on the ears, can now be checked on the screen, improving accuracy and speed. On the other hand, some argue that this has led to a relative decline in the importance of ““techniques for adjusting by ear.’’
また、音源の入手方法も変化した。オンラインストアの普及により、世界中の楽曲を即座に購入・ダウンロードできるようになり、地域的な制約は大きく緩和された。
Music has changed from physical objects to data, and the working environment of DJs has been fundamentally restructured.
コントローラー文化とインターフェースの変容
As software evolves, dedicated MIDI controllers appear. This gives DJs a new interface that doesn’t rely on traditional turntables.
Trigger samples with pads, manipulate complex effects, subdivide loops, etc. The controller has changed from a device used to ““play” songs to an instrument used to ““manipulate” songs. This change blurred the line between DJing and live performance.
さらに、複数のデッキを同時に操作することが容易になり、マッシュアップやリアルタイムリミックスといった手法が一般化する。DJは既存の楽曲を組み合わせ、新たな構造をその場で生成する存在へと進化した。
At this stage, the role of the DJ has clearly changed. He has become more than just a music selector, he has become a performer who edits music in real time.
インターフェースの変化は、音楽の扱い方そのものを変えていった
Streaming Era: An Endless Catalog
In the late 2010s, the center of music consumption shifted to streaming. Services such as Spotify and Beatport have also influenced DJs’ sound source management.
Some DJ software now integrates with streaming, allowing you to play songs without having to store them locally. This will give DJs access to a catalog of tens of millions of songs.
However, this convenience also created new challenges. These include dependence on internet connectivity, audio quality issues, and licensing restrictions. In addition, the endless options also made it more difficult to choose songs.
In the past, the optimal selection of songs was made from a limited number of records, but now it is necessary to decide ““what not to select’’ from a huge number of songs.
Infinite options have made the act of selecting music even more meaningful.
AI and automation: the future of music selection
In the 2020s, AI technology is starting to have an impact on DJ culture. Automatic beat matching and key analysis have already become standard features, making it possible for even beginners to mix with a certain level of quality.
さらに、AIによる楽曲推薦やプレイリスト生成は、選曲プロセスそのものを変えつつある。アルゴリズムは膨大なデータをもとに最適な楽曲を提示するが、それはあくまで統計的な最適解である。
In the space of a club, non-numerical elements such as audience reaction and atmosphere are important, and it is difficult to completely reproduce these with an algorithm.
Therefore, AI is not positioned as a replacement for DJs, but as a supporting tool. The final decision is still left to humans.
As technology advances, the value of human intuition increases relatively.

Conclusion: DJing as an art of choice
The digitalization of DJ culture is not just a technological advance, but also a change in the relationship with music. Freed from physical constraints, DJs now have more freedom than ever before.
But that freedom also comes with responsibility. What to choose from the infinite options and how to arrange them? That judgment is what determines the value of a DJ.
In the past, the selection of record bags was naturally narrowed down due to physical constraints. Nowadays, that restriction has disappeared, but the importance of choice has actually increased.
A DJ is not someone who plays music, but someone who edits time and space. That essence remains unchanged even in the digital age.
What remains after digitalization is the artistry of the act of selection itself.
