[Challenge] A compilation of Vocaloid songs that are difficult to sing

One of the appeals of Vocaloid is that it sings exactly as the creator intends.

Because of that, there are tons of songs built with innovative vocal work—like high tones and ultra-fast melodies that are hard to reproduce with human vocal cords!

This time, we’re introducing Vocaloid songs that are difficult to sing!

It’s recommended for those who want to challenge their limits or acquire new forms of expression.

It might be surprising, but slow ballads also make an appearance.

Be sure to check it out to the end!

[Challenge] A Compilation of Vocaloid Songs That Are Hard to Sing (21–30)

Panopticonr-906

Panopticon resonates with a sound that matches VOCALOID’s mechanical aesthetic.

Created in 2019 by Vocaloid producer r-906, who specializes in electronica-based music, it features a driving sound propelled by a surging bassline intertwined with dynamic drums.

The track leverages mechanical vocalization—such as counting letters in romanization one by one—making it challenging to sing.

The key is to focus on staying in the groove and maintain a steady level of intensity.

Why not try singing this one-of-a-kind Vocaloid track that blends human emotion with the uniquely mechanical sound only VOCALOID can offer?

CH4NGE resounds with a sound that evokes a glamorous clubhouse dance floor.

Created in 2021 by Giga, a Vocaloid producer with numerous hit songs, it features Hatsune Miku’s sultry, cool vocals riding over a heavy electronica sound—truly striking.

While the song unfolds through various sections, you’ll sing it well if you keep the four-on-the-floor beat in mind.

The lyrics feature plenty of rhymes, so it’s also helpful to memorize and practice the repeated phrases.

Try delivering a performance that balances passion with cool composure for your audience.

Sequelae, memo, time bomb.Satsuki

Sequelae, a memorandum, a time bomb. / Hatsune Miku · Kaai Yuki
Sequelae, memo, time bomb.Satsuki

Vocaloid producer Satsuki’s work “Aftereffects, Memoir, Time Bomb” is a piece that carefully portrays the darkness of the heart.

The first half depicts a gloomy atmosphere over a near-futuristic sound.

From the second half, it modulates into an intense sound, building to a climax that features ultra-high-speed singing.

Try listening while pondering the meaning behind the title and the division of vocals between Hatsune Miku and Kaai Yuki.

By the way, the latter half is quite fast-paced, so I recommend starting with the music video that displays the lyrics.

Super Protagonist feat. Hatsune MikuPinokio P

PinocchioP – Super Superhero feat. Hatsune Miku / Super Superhero
Super Protagonist feat. Hatsune MikuPinokio P

Currently popular in the Vocaloid community as a seemingly eccentric yet deeply meaningful masterpiece, “Super Protagonist feat.

Hatsune Miku” is a new song by the well-known Vocaloid producer PinocchioP, featuring an ostentatious, flashy melody.

While the vocal line contains no long sustained notes, it involves drastic pitch changes and stays in a consistently high range, making it highly challenging.

Rather than being difficult for hitting high notes per se, it’s the continuous production of high notes that poses the real challenge.

Consider adding it to your repertoire.

Kaikai KitanEVE

This song was pre-released on October 3, 2020, and serves as the opening theme for the first season of the TV anime Jujutsu Kaisen.

I think many people often sing Eve’s songs, but all of them have a very wide vocal range, don’t they? By the way, Kaikai Kitan spans from F2 to D5, which made me think, “Can you really sing that low?”—I was surprised too.

It’s a song that’s challenging in the low notes of the A section and the high notes of the chorus.

In the A section, try to let the voice come out slowly from the vocal folds and avoid making it too muffled.

From the B section, it starts to sound more song-like with higher notes, but if you push too hard, your voice will collapse.

Aim to project your falsetto strongly and focus on explosiveness! The chorus is also demanding in terms of breathing, so it might be good to decide in advance where you’ll take breaths.

For songs where breathing is tricky like this, instead of singing everything at 100%, it helps to pace yourself and take small, solid breaths in the brief moments you have!

PlayPikon

Picon – Playback ft. Hatsune Miku

“Playback,” produced in 2021 by Vocaloid producer Picon, who is known for songs with a unique worldview, depicts scenes of recalling days spent with a loved one and sings of a reality that feels like a dream.

Within its soundscape tinged with traditional Japanese ambience, the heartrending melodic lines are sure to bring tears.

Though the song unfolds at a slow tempo, sustaining a gentle, high register throughout is challenging.

It’s a grand ballad featuring Hatsune Miku’s crystalline vocals that resonate with feelings so moving they could draw tears.

Why not take on this song, imbued with beautiful yet fragile emotions?

A rare predation scene of the Scorpion GirlSTEAKA

Let’s turn up the volume and enjoy some hardcore electronic music! This track by Vocaloid producer STEAKA was released in 2022.

It placed 5th in the “VocaColle 2022 Autumn” rankings.

The contrast between the forceful, high-pressure synths and Hatsune Miku’s whispery vocals is superb.

Without balancing crisp articulation and composure in the singing, you might not be able to convey the song’s cool vibe.

Listen closely to how each individual word is voiced.
