Challenge your limits! A collection of Vocaloid songs with high keys and soaring high melodies

Many people probably have the impression that “Vocaloid songs have high keys.” In fact, the pitch range you can manipulate with synthetic vocal software is quite wide.

If you own one, you know—you’ve probably tried making it sing at absurdly high pitches, right? In this article, I’ve put together a list of Vocaloid songs with high keys! I think it’s a playlist that can help you choose songs for karaoke or cover videos.

Strictly speaking, in music theory there’s a difference between “a melody that includes high notes” and “a song with a high key,” but I’ve kept things loose here to be more accessible.

By all means, challenge the limits of your own vocal cords!

Pushing the Limits! A Collection of Vocaloid Songs with High Keys and Soaring High-Melody Vocals (41–50)

Rin Kagamine - Meltdown (Original)
Core Meltdown iroha (sasaki)

The first thing that stands out about this song is Kagamine Rin’s voice, which rings out high and far.

While the lyrics are abstract, they are said to express the journey from childhood to adulthood and the moratorium in between, drawing many listeners in.

As the title “Meltdown” suggests, the lyrics include uncommon words like “fusion reactor.” Alongside those, you’ll also find everyday phrases.

Dive in and fully enjoy the world depicted there.

Speaking of Nayutan Seijin, they’re a well-known creator famous for crafting songs characterized by digital rock sounds that make heavy use of electronic tones.

This track is a pop tune with those very traits, and as the title includes “Alien,” it takes on a slightly mysterious air as well.

You might brace yourself, wondering what kind of message rides on such a sound—but the lyrics, filled with irresistibly cute feelings, will surely leave you warm and fuzzy.

A love in tempo: sprightly, adorable, and a little uncanny.

It’s a song not only to listen to, but one you should try singing, too.

Toumei Elegy n-buna

This is a poignantly melancholic track sent out into the world by n-buna, who is active as a member of the band Yorushika.

Many listeners have likely found their tears welling up at the song, woven with a voice that sounds almost as if it’s crying—husky and fragile.

Yet it’s not merely a sad song; it feels as though it spills out the raw feelings from deep within the heart, culminating in a piece that radiates tremendous energy.

Let yourself be overwhelmed by this song’s extraordinary intensity, a force powerful enough to crush those who listen.

If you’re looking for a stylish Vocaloid track, this is the one.

It’s a song by the Vocaloid producer Surii, also known for the hit “Telecaster B-Boy,” released in 2019.

The title hints at it, but the glamorous sound that evokes a city night is insanely cool! The arrangement never gets old, featuring phrases with hints of jazz and rock—another big part of its charm.

The key is high, but don’t worry about that—just sing it with full energy and groove!

Romeo and Cinderelladoriko

Even now, long after its release, this song remains popular as a legendary track in the Vocaloid scene.

Created by doriko, whose wide-ranging musicality is widely admired, it was released in 2009.

It features a grand arrangement that blends a band sound with strings.

The lyrics are packed to the brim with a girl’s feelings for the person she loves—a cute yet slightly bittersweet love song.

The chorus includes especially high notes.

If you plan to sing it, be sure to carefully check your breathing points.

PinocchioP – SLoWMoTIoN feat. Hatsune Miku / SLoWMoTIoN
Slow Motion PinocchioP

Despite being catchy, it’s incredibly original—a highly inventive piece.

It’s a song by PinocchioP, a Vocaloid producer who also works professionally as a composer, released in 2014.

The lively soundscape, colored with band sounds, call-and-response interjections, and bleepy-poppy tones, is delightful.

It’s fun just to follow what timbres pop up.

The lyrics, which reflect on the passing of time and on life, blend uniqueness with depth.

In the original key, I think the chorus is especially challenging.

Chinozo “Mushi” feat. Kotoha Akane & Aoi
Mushi Chinozo

Vocaloid producer Chinozo, whose name became widely known after “Goodbye Sengen” entered the Hall of Fame, went million, and surpassed 100 million streams.

Chosen as the official demo song for NEUTRINO’s free speech-synthesis voices Kotonoha Akane and Aoi, “Mushi” exquisitely contrasts a driving 8-beat rhythm with an ear-catching ensemble.

The melody is both complex and high-pitched, making it difficult even if you lower the key for karaoke.

The breathing timing is also tricky, so be sure to prepare a strategy beforehand if you decide to take on the challenge.
