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!

Challenge Your Limits! A Collection of Vocaloid Songs with High Keys and Soaring Melodies (31–40)
collapse; fainting spell (colloquial/slang)iyowa
A track by Vocaloid producer Iyowa, who made their debut in their second year of high school and took their name from having a weak stomach.
The slightly unstable yet cute intro, the catchy pop melody that sticks in your ears, and the arrangement that seems to blend both drive and weightlessness make a strong impression throughout the song.
With its fast tempo, high key, and tricky elements like sudden beat changes mid-song, you might find it difficult to sing perfectly at karaoke.
However, precisely because of that, it feels great if you can make it through—so try singing it with the intention of pushing your limits.
Maiden AnatomyDECO*27
Why not try your hand at a yandere-flavored love song? This piece by DECO*27, a Vocaloid producer behind numerous hits, was released in 2019.
It’s a fan favorite also featured in the mobile game Project Sekai.
The mix of rock built on a four-on-the-floor rhythm is insanely addictive, and Miku’s slightly mature vocals shine.
The chorus reaches high notes, but the melody is easy to remember, so definitely give it a try to level up your singing!
Alice in the FreezerOrangestar
An intro marked by the softly resonant piano notes—“tan… tan…”—leaves a striking impression.
From there, you can imagine a story unfolding in a cold, unfamiliar world that’s about to begin.
The uninterrupted flow of tones and the satisfying clarity of the vocals laid over them create a comfort that’s simply irresistible.
As the creator described it as a “Frozen Nonsense Theater,” the song sometimes proceeds exactly as we expect, and at other times boldly subverts those expectations, offering surprise and delight.
It’s a challenging song to sing, but it’s one that makes you want to try and present your own expression.
KINGKanaria
A high-sense dance tune that makes your body move on its own.
It’s a track by Vocaloid producer Kanaria, who drew attention with the debut song “Hyakki Matsuri,” released in 2020.
Its biggest hallmark is the rolled-tongue style of tuning.
The vocal work, which at times even sounds like English lyrics, blends with the stylish sound to create a one-of-a-kind world.
As you’d expect from a fast-tempo song, the melody is full of speed as well.
It’s a Vocaloid track with a fairly high difficulty level to sing at karaoke.
I’ve been alive for 1,000 years.iyowa
The key height is one factor, but the off-axis rhythms also contribute to the increased difficulty.
This song, released in 2020, is by Iyowa, a Vocaloid producer whose distinctive style captivates listeners and won’t let go.
Centered on a girl who has lived for a thousand years in a painted world, its mysterious setting is addictive after just one listen.
Iyowa’s songs are all challenging, but because they’re popular there are many cover videos, so definitely search around and use your favorites as references.

DramaturgyEVE
From the guitar phrase that sways left and right in the intro, you’re instantly drawn into the song’s world.
It’s one of the signature tracks by Eve, a popular Vocaloid producer who’s also active as a singer-songwriter, released in 2017 and included on the album Bunka from the same year.
The sound arrangement blends literary lyrics with rhythmic flair, stylishness, and a sense of speed—its charm is undeniable.
It’s a highly addictive number that makes you want to listen on repeat.
The Vocaloid version, not the one sung by Eve himself, is set in a higher key.
