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!

Imagination Forestjin

This is a work by Jin, also known as Shizen no Teki-P, whose Kagerou Project series sparked widespread attention through its multimedia expansion, and it was released in 2012.
It’s a refreshing song that unfolds a boy-meets-girl story.
Just listening to it, you might not think it goes that high, but especially in the latter half of the chorus, some quite challenging high notes appear.
If you sing it at karaoke, using falsetto might be a good idea.
By the way, there are arrangement variants titled “Mousou Forest” and “Kuusou Forest,” so enjoy those together as well.
I don't know anything about music.Iori Kanzaki

Vocaloid producer Kanzaki Iori, known for poetic songs with strong storytelling, has drawn significant attention.
His signature track, “Inochi ni Kirawarete Iru” (“Hated by Life Itself”), has been covered by many artists, including the singer Mafumafu.
Among his works, the song best known for its high key is “I Don’t Understand Music.” It was included on the 2019 album “Hakushi” (“Blank”).
Its straightforward band sound unfolds at a slow tempo and strikes straight to the heart.
Hatsune Miku’s high notes, carrying a sense of longing, are absolutely swoon-worthy.
Although the key is high, the melody develops within a fairly consistent range, making it a great recommendation for those trying high-tone vocals for the first time!
AceYugika

Vocaloid producer Yugika, whose debut work was inducted into the Hall of Fame.
“Ace” is Yugika’s third piece, released on January 30, 2022.
The consistently driving drum beat has a great groove that will make you want to move your body.
The urbane piano timbre also gives the track a distinctly stylish flair.
The highest note in “Ace” is hihi A, A5.
It only appears for a moment, but the melodic leaps are another factor that makes this song challenging.
It’s a piece that demands precise, detailed technique.
Fabric FlowerHiiragi Magnetite

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.
Rebellion at 22Tohta Kasamura

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.
Hollow SleepNuyuri

“Hollow Sleep” is a song by the Vocaloid producer Nuyuri, who is also known as the arranger of ZUTOMAYO’s “Byoushin wo Kamu” (Biting the Second Hand).
The video was released on Nico Nico Douga and YouTube in 2020.
It’s a cool track with stylish chord voicings and a tight groove, but the chorus is extremely high.
The verses and pre-chorus aren’t that high, yet the moment the chorus comes in, the range shoots up dramatically.
That contrast is striking and gives the song an addictive quality that makes you want to listen again.
Then I hope your ideology dies.Shino Mirin

An intense EDM beat carries an aggressive melody that stirs your fighting spirit just by listening.
“Then your ideology should die” is a track released on December 12, 2020, by Shiino Kumo, who has been active as a Vocaloid producer since the age of 13.
The fast tempo and frequent shifts in tone alone may feel challenging to keep up with.
The song’s highest note is hi D#, D#5.
If a male singer tries to hit this note in chest voice, it might strain the throat.
Incorporating falsetto or mixed voice, or setting the key to -3, will make it easier to sing!
