【コラム】 US HipHop（アメリカヒップホップ）の歴史：地域・クラブ・メディア・機材を含めた全体像

History of American hip-hop: Overall picture including regions, clubs, media, equipment, etc.

文：mmr｜テーマ：アメリカでの地域ごとに異なるスタイルが形成されたヒップホップについて

Hip hop was born in the Bronx, New York in the late 1970s, and has developed into more than just a music genre, it has also become a culture linked to dance, graffiti, fashion, and social movements. アメリカでは地域ごとに異なるスタイルが形成され、クラブシーンやラジオ、デモテープ、そしてレコード文化が発展を支えました。また、サンプリング技術の発展とその後の脱サンプリングの流れは、ヒップホップの音楽的革新を象徴しています。

Late 1970s: The origins of the Bronx and the foundations of club culture

Region/era background

ブロンクス地区の若者たちが、廃れた公共スペースやコミュニティセンターでDJパーティーを開催。ブロークン・ビート（ブレイクビーツ）を繰り返すことで、B-Boy/B-Girlたちのダンスが進化しました。 Clubs and block parties were more than just music venues; they were a symbol of community unity.

The importance of radio and demo tapes

当時のヒップホップはラジオ番組（例：WBLSの「The Show」）で広まり、デモテープがアーティスト発掘の重要な手段でした。 DJクール・ハークやAfrika Bambaataaは、自らのミックステープを地域のラジオやパーティーで流し、情報拡散に寄与しました。

代表的な名盤

The Sugarhill Gang”Rapper’s Delight”(1979)

Grandmaster Flash and the Furious Five “The Message” (1982)

Equipment/Sampling Culture

Technics SL-1200ターンテーブル、MPC初期型、ドラムマシン（Roland TR-808）が登場。レコードからのサンプリングが音楽制作の中心となり、DJはレコードの「ブレイク」部分を繰り返す手法を確立。

1980年代：東海岸の黄金期と西海岸の台頭

East Coast (New York)

Public Enemy and Eric B. & Rakim appeared, and rap with political and social messages was born. The club also served as a place to try out new beats.

West Coast (California)

ギャングスタ・ラップが発展。N.W.A.やIce-Tが現れ、ComptonやLos Angelesのストリート現実を描写。 A unique G-funk style was honed in the clubs and rolling parties of the West Coast.

Role of demo tapes and radio

The new song was aired on local radio stations (KDAY, KMEL), and young people who listened to the demo tape spread it by word of mouth. In particular, local radio DJs acted as referees of the scene.

Representative masterpiece

Run-D.M.C. “Raising Hell” (1986)

Public Enemy “It Takes a Nation of Millions to Hold Us Back” (1988)

N.W.A.『Straight Outta Compton』(1988)

Sampling culture

Extract phrases from soul, funk, and jazz records using a sampler (Akai MPC60/SP-1200). Record culture was at the core of production, and DJs’ knowledge of records was directly linked to their technical ability.

1990年代：東西対立と南部の興隆、クラブとレコード文化

East Coast vs. West Coast

The Notorious B.I.G.と2Pacの対立が象徴するように、地域間の緊張が音楽に影響。 New York clubs (Tunnel, Limelight) became venues for rap battles and the premiere of new releases, fostering a rap battle culture.

South (Atlanta, Houston, New Orleans)

OutKastやUGKが登場し、独自のサウンドを確立。クラブでのテープ流通が地域ヒップホップの拡散を支えました。

脱サンプリングへの動き

Due to copyright issues and rising costs, an increasing number of artists are turning to original sound source production and live performance. Dr. Dre’s ““The Chronic’’ (1992) skillfully uses sampling, while G-funk uses a lot of synths and original bass lines.

Representative masterpiece

East Coast: The Notorious B.I.G. “Ready to Die” (1994)

West Coast: 2Pac “All Eyez on Me” (1996)

South: OutKast『ATLiens』(1996)

2000s: Digitalization and diversification of the club scene

クラブ文化

DJ sets evolved at clubs in New York and LA. In an era before radio and streaming, songs became a buzz on club floors. Before demo tapes and the internet, rap battles were centered around clubs.

De-sampling and equipment changes With the spread of DAWs (Pro Tools, Ableton Live), it is now possible to create unique sound sources using synths and plug-ins without relying on sampling. This increases the proportion of original beats.

Representative masterpiece

Jay-Z “The Blueprint” (2001)

OutKast”Speakerboxxx/The Love Below”(2003)

2010s-Present: Streaming Era and Globalization

Combining club and online culture

Mainly released digitally on SoundCloud, YouTube, Spotify, etc. The club immediately changed its role as a place to see reactions. Battle Rap and Freestyle are distributed online and are appreciated beyond regional differences.

Equipment/production environment

Software synth (Serum, Omnisphere)

DAW (Ableton Live, FL Studio)

Expanding the use of plugins and sample packs

代表的な名盤

Kendrick Lamar “good kid, m.A.A.d city” (2012)

Migos”Culture”(2017)

地域・クラブ・メディア・制作手法の総合的影響

East Coast: Breakbeat, social rap, record sampling culture

西海岸：ギャングスタ・ラップ、G-funk、クラブでのローリング・パーティー

Southern: Trap, tape distribution, unique sense of rhythm

Clubs and radio: A place for dissemination and dissemination, a hotbed of freestyle culture

Sampling → De-sampling: Evolution to original production due to copyright issues and technological innovations

Hip-hop is a culture that has evolved through a close intertwining of regions, clubs, media, and equipment, and is expected to continue to expand with new technology.

Specific examples of sampling copyright lawsuits

Grand Upright Music v. Biz Markie (1991) Gilbert O”Sullivan”s “Alone Again” unauthorized sampling lawsuit. Since then, it has been clarified that samples without permission are illegal.
Bridgeport Music v. Dimension Films (2005) Funkadelicのギターループを無断使用した事件。サンプルは「一秒でも無断使用禁止」と判例化。
The Turtles v. De La Soul (1989~Settlement) “Transmitting Live from Mars” における無許可サンプル。De La Soulは以降長年デジタル配信困難に。

Role of mixtape culture

DJ Clue, DJ Drama, DJ Screw らによるミックステープは90s以降アンダーグラウンドからメインストリームへの橋渡しとなった。
Southern (Houston, ATL) ““Screw Tape” and ““Gangsta Grillz” formed the scene, making it possible to discover artists independent of labels.
In the 2000s, Mixtape transitioned to “SoundCloud” and “DatPiff” and evolved into a means of promotion in the Internet era.

Waveform comparison of typical hip-hop beats

Although it is text-based, it is expressed with pseudo waveforms that are conscious of sine waves and square waves. You can visually understand the evolution of rhythm in hip-hop.

Conclusion

Hip-hop has evolved to reflect the culture and social background of each region. The East Coast, West Coast, and South each have their own unique styles, which have influenced not only music but also fashion, language, and social movements. Hip-hop will continue to evolve as new techniques and expression methods emerge.
