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

Charlesbarūn

Charles / Balloon (self cover)

The Vocaloid song “Charles” has become very popular thanks to covers by many singers and artists—are you familiar with it? I always sing it in the original key, but it’s quite difficult! The range is C#3 to C#5, and it’s very high overall, but I especially find the parts in the chorus where the melody jumps up and down to be challenging.

There are also spots near the beginning of the A section where the notes rise.

For those sections, it feels good to produce the sound if you visualize the pitch you want and “hit the target” with your voice like shooting an arrow.

Also, the rhythm in the B section tends to rush, so try to keep the tempo by singing each note carefully.

Most Vocaloid songs are high, but if you’re confident in your high notes, you might be able to sing “Charles” in the original key—so give it a try!

Sequelae, memo, time bomb.Satsuki

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

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.

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?

Six Trillion Years and an Overnight Storykemu

[HD] Six Trillion Years and One Night Story [IA Original Song / with PV] - KEMU VOXX

Released in December 2012, this song is a classic, notoriously difficult Vocaloid track! It has a Japanese-style vibe with a very relaxed intro, but the tempo suddenly speeds up and the lyrics become extremely dense.

You’ll need to be mindful of stamina, lung capacity, and quickness, but it’s highly recommended if you love fast songs! The key to singing the rapid-fire sections is not to try to articulate every single consonant, but to clearly pronounce the vowel sounds that carry the accents.

That will help you lock into the rhythm and sing more lightly.

With fast-tempo songs, above all, you have to memorize the lyrics; otherwise, when you sing it at karaoke, you’ll end up just chasing the words and sounding vague.

I recommend first being able to hum the melody, then adding the lyrics afterward!

Super Protagonist feat. Hatsune MikuPinokio P

PinocchioP – Super Superhero feat. Hatsune Miku / Super Superhero

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

Kaikai Kitan – Eve MV

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!

A rare predation scene of the Scorpion GirlSTEAKA

A rare predation scene of a scorpion girl / miku

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.
