Nightcore

Published September 8, 2026

Nightcore refers to Eurodance and trance tracks sped up to 160-180 BPM with pitched-up vocals, a style two Norwegian teenagers invented for a 2001 school project. Fan uploads under the name grew into one of YouTube's largest music subcultures, defined by anime-girl thumbnails and a strict speed-and-pitch remix formula.

Overview

Nightcore edits follow a strict recipe. Producers take an existing Eurodance, trance, or pop song, raise the tempo to somewhere between 160 and 180 beats per minute, and shift the vocal pitch upward so the singer sounds cartoonishly high4. The visual half of the format is just as fixed. Most YouTube uploads pair the audio with a still image or slow slideshow of anime girls, often lifted from visual novels or shoujo series2. Urban Dictionary catalogues three subvariants fans use to describe the sound: 'Pure Nightcore' with extreme speed and chipmunk vocals, 'Bass Nightcore' that layers heavy low end under the sped-up top, and 'Trance Nightcore' that keeps runtimes long and repetitive2.

Debate over whether Nightcore counts as a music genre or just a remix process runs through fan forums. Discussion boards from the early 2010s argued that speeding up someone else's track hardly qualifies as making new music, while defenders pointed out that fans developed shared rules around tempo, artwork, and mood3. The label also drew criticism because many uploads strip credit from the original artist, turning YouTube channels into ad-revenue streams built on music the uploaders did not make2. That tension between fan love and the copyright question shaped how Nightcore spread across the platform.

Nightcore started in 2001 as a school project by Thomas S. Nilsen and Steffen Ojala Søderholm, two Norwegian classmates from the north of the country who were both born in 19861. Their first track earned less than top marks, so the pair went back and produced a full 13-track EP called Energized, which brought them the top grade on the second attempt1. The duo kept the Nightcore name, which they said meant 'the core of the night, so you'll dance all night long'4.

Nilsen took the alias DJ TNT and Søderholm went by DJ SOS. In a 2011 interview with The Super Super, they said their teenage inspiration was the German happy hardcore act Scooter, whose high-pitched vocal hooks they wanted to hear more of1. Neither of them partied at the time, so they mixed music for their own listening rather than for any club scene1. The pair burned CD copies of Energized and follow-up records and handed them to local DJs and anyone who asked, without selling or promoting the releases1. The original Nightcore MySpace page from the late 2000s survives on the Internet Archive6, and albums like Caliente are still catalogued on Last.fm5.

How It Spread

The duo's small-scale Norwegian project turned into a global YouTube trend around the mid-2000s, when fans began posting their own sped-up remixes under the Nightcore label after hearing the original CDs4. By 2011, The Super Super reported 'tens of thousands' of tracks tagged Nightcore on YouTube, with many uploads pulling in millions of views1. Fans as young as 13 were producing tracks in GarageBand or other free tools, treating anything from Lady Gaga to ABBA as raw material for a Nightcore edit1.

Anime fan communities picked up the aesthetic in parallel. Threads on itjustbugsme in the early 2010s complained that Nightcore was 'basically just sped-up music with an anime girl picture slapped over it,' arguing the label often had more to do with weeaboo iconography than musical craft3. Forum posters also debated whether songs sounded better sped up, with some admitting that certain tracks got more interesting under the treatment even when the vocals turned into chipmunk squeaks3. The pattern of anime-girl thumbnail plus sped-up dance track hardened into the visual signature that made a Nightcore upload recognisable at a glance2.

The uncredited-remix model kept drawing criticism. Urban Dictionary entries describe uploaders as 'moneyholics' who slap anime imagery on other people's music to claim ad revenue while the original artists get nothing2. Even so, the Nightcore name became a shorthand for the whole sped-up EDM style, and a wave of copycat '-core' labels followed on YouTube as fans applied the same treatment to other electronic subgenres.

How to Use This Meme

A typical Nightcore edit starts with an existing track, most commonly Eurodance, trance, happy hardcore, or a pop song with a strong 4/4 beat. Producers speed the track up by roughly 15 to 20 percent in a DAW like GarageBand, Audacity, or FL Studio, which raises the pitch of the vocals along with the tempo so the singer sounds much younger and higher1. Some editors add heavier bass or trance-style repetition on top, matching the 'Bass' or 'Trance' subvariants that fans use2. The finished audio is paired with an anime image or a short looping animation and uploaded to YouTube, usually with the artist name followed by '(Nightcore Remix)' in the title2. Crediting the original artist in the description is common but not universal, which is why the practice draws regular criticism from listeners who feel the uploaders are cashing in on other people's work2.
