Life / Miku Rin Len Luka MEIKO KAITO Boss Rush by gcmstyle (Amemelts-P) [Project SEKAI ULTIMATE Selected Song] (JINSEI [Our Life])

You can’t predict how it will unfold—in fact, it’s a piece that crams a variety of musical styles into a single track.

It’s a song by gcmstyle, also known as Anmeltz-P, released in 2022.

It drew attention when it was selected for the ultra-difficult song contest “Project Sekai ULTIMATE.” It kicks off with a fiery mixture rock vibe, then shifts into a bright, cheerful A-melody.

From there it jumps to hip-hop, blisteringly fast electro with a super high-speed melody, EDM with English lyrics, metal, a piano ballad—the style keeps changing at a dizzying pace.

It’s a short track, but the sense of satisfaction you feel after listening is absolutely off the charts!

Spring Storm / Hatsune Miku

Jhon is a Vocaloid producer who also provides songs to artists under his solo project TOOBOE.

His 2019 release “Shunran” is a poignant Vocaloid track themed around springtime farewells.

It features a driving electronica sound paired with Hatsune Miku’s rhythmic vocals.

Because the lyrics unfold rapidly, the breathing spots can be tricky.

The key is to deliver crisp, articulate singing that follows the melodic progression.

It’s a Vocaloid song with a bittersweet yet resonant melody—be sure to give it a try.

CharlesBalloon

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!

TetrisHiiragi Magnetite

Tetris / Kasane Teto SV

Right now, the most talked-about Vocaloid track is “Tetris.” It’s a new song by Hiiragi Magnetite, characterized by a flashy sound that carries a touch of denpa-style essence.

While this piece doesn’t necessarily feature ultra-high phrases, it’s packed with high lines throughout, and the pitch leaps are extremely sharp, giving it an overwhelming level of difficulty.

With few break points, it also demands strong lung capacity—another challenging aspect.

Be sure to add it to your repertoire.

Super Protagonist feat. Hatsune MikuPinocchioP

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!
