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.

Loveka? / Hiiragi Kirai feat. flower

“Loveca?” is known as one of the signature songs by Hiiragi Kirai, a Vocaloid producer with numerous hits.

The track drew attention alongside a cover version by Ado.

It unfolds a hefty electro sound laid over the breezy rhythm characteristic of swing jazz.

Mastering Flower’s vocals, which display a wide range of expressions, can be challenging.

In the chorus, where rhyme is used frequently, the key is to deliver a rhythmic performance without running out of breath.

Why not try tackling a Vocaloid song that takes a cynical look at themes like “love” and “lies”?

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!

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!

Panopticonr-906

Panopticon / Hatsune Miku

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?

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!

CH4NGEGiga

Giga – CH4NGE ft. KAFU [MV]

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.
