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!

Push Your Limits! A Collection of High-Key, High-Pitched Vocaloid Melodies (71–80)

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.

Vocaloid producer Tsumiki, whose debut work “Tokyo Diver Fake Show” shot straight into the Hall of Fame and drew attention for its stylish musicality, has been making waves.

His seventh track, “Ungray Days,” released on May 16, 2020, features a tight rock ensemble with edgy guitar sounds that really get your energy up.

With its high key and relentless, driving melody, it truly embodies the essence of a Vocaloid number.

While it’s quite challenging for a flesh-and-blood singer to tackle at karaoke, it’s a track that lets you experience the fun of singing Vocaloid songs.

Tota Kasamura’s “The Day I Cried for the First Time” stimulates and moves the listener’s heart at the same time.

It’s a gently flowing ballad, and as you listen, you’ll find yourself crying naturally.

The lyrics are sprinkled with faint memories of youth and resonate as if staying close to the listener’s heart.

Isn’t it wonderful to be able to sing a song like this so naturally?

Vocaloid producer Hiiragi Magnetite, who uses the Vocaloid KAFU with a girlish singing voice, has gained popularity for songs like his signature track “Marshall Maximizer.” Among his works, one of the highest in key is “Fabric Flower,” produced in 2021.

Its jazzy tones marked out in a rhythmic tempo are addictive.

Rin Kagamine’s performance, delivering highly narrative lyrics, is heart-melting.

Since the chorus is set in a high key, it’s also recommended to practice it by breaking it into phrases.

This is a legendary Vocaloid rock track with an incredibly sharp, badass sound.

It’s a song by wowaka, a Vocaloid producer who also performed as the frontman of the band Hitorie, released in 2011.

This is exactly what “stylish” means—relentless song structure, high-speed melodies—it’s electrifying.

And yes, the key is high, and the melody is fast! Among the many Vocaloid songs out there, this one might be particularly difficult to sing.

Make sure to practice well!

Dynamic Ji-enz is a music project set up as a band by Carlos Hakamada.

The video drawing attention on their YouTube channel is “∞ Mawaru ∞.” It’s a song themed around sushi, comically depicting plates circling on a conveyor-belt sushi lane.

The vocals use Hatsune Miku and Otomachi Una, featuring ultra-high harmonies.

It’s a level of singing that humans would find hard to produce.

Also unique is the band member introduction during the instrumental break.

Rebellion at 22Kasamura Tōta

Vocaloid producer Tota Kasamura sublimates the stinging parts within the heart into beautiful melodies.

The 2019 song “22-year-old Rebellion” is a track that sings about feelings on what it means to become an “adult.” True to Kasamura’s style, the delicate choice of words pairs beautifully with the piano accompaniment.

The highest note in this piece is hihiA, A5.

Because the range is quite high, it’s safe to say this is a difficult song.

It will likely be right on the edge of whether you can hit the notes or not.

Please give it a try.
