[Taking on Songs with a Wide Vocal Range] S-Rank Challenge Songs (21–30)

Queen Bee is a rock band highly acclaimed for their original musicality.

Artists with high-pitched voices are fairly common in the Japanese music scene.

However, Queen Bee’s vocal lines don’t just sit in a high range; they demand a wide span from very low to extremely high.

Among their works, the particularly challenging piece is Kaen (Flame).

With an extremely high chorus that uses falsetto and verses (A and B sections) that drop into low tones, the contrast is stark, making its difficulty indisputably S‑class.

Satsuki, a Vocaloid producer known for upbeat tracks, has released a new song, Mesmerizer.

Featuring Hatsune Miku and Kasane Teto, it showcases Satsuki’s signature style with a lively, highly danceable melody throughout.

The piece also includes extremely high vocal ranges.

With its fast-paced vocal lines—typical of Vocaloid and difficult for breathing—very few human singers could perform it perfectly.

There’s also a key change in the latter half, so if you’re confident in your high range and lung capacity, give it a try.

UNDEADYOASOBI

YOASOBI’s new song “UNDEAD.” Released as a theme song for the Monogatari Series, it emphasizes electropop elements even more than their usual tracks.

The trickiest aspect of this piece is, above all, the intense leaps in pitch.

The vocal range is quite wide, but even more challenging is the switching between chest voice and falsetto.

Since the song demands considerable pitch control, it’s best to listen closely and thoroughly before attempting it.

Kaikai KitanEVE

Eve is known as a singer-songwriter and composer.

The song he wrote specifically as the opening theme for the anime Jujutsu Kaisen is Kaikai Kitan.

The track captures the protagonist’s inner turmoil and conflict, which is why the pitch shifts so dramatically.

It also features the driving, fast-paced melody typical of shonen anime openings.

The sense of speed comes not only from the quick melody but also from the gradually rising key.

With its rapid tempo and drastic pitch changes, it goes without saying that the song is quite difficult.

Vocaloid producer Satsuki, known for compositions that incorporate ultra-high notes, has gained widespread popularity with “Mesmerizer,” and now they’ve dropped another hit.

That’s the new track “ObsoMeat.” It’s a piece that sustains high notes on par with the previous work, and the chorus in particular features overwhelmingly high pitches.

From a human perspective, it’s an unrelenting barrage of extremely high tones that could make your temples ache, so it’s recommended for anyone wanting to build endurance in high-register parts.

Be sure to check it out.

LuluAdo

Ado’s hit number “Ruru.” It’s a song that vents frustration with the world’s absurd rules, marked by an extremely hard-edged musical style.

This piece also spans a very wide vocal range.

While many people can handle songs that are simply high, the standout feature here is how raw and aggressive the high parts are.

It doesn’t just demand pure high notes; it calls for a wide range of expression—like falsetto blended with shouts—so solid fundamental vocal skills are required.

If you’re confident in your singing ability, be sure to check it out.

chantAdo

Ado is one of the female singers most supported by the younger generation.

While most vocalists in Japanese music tend to sing with a light and gentle touch, her style is characterized by frequent use of high-difficulty shouts.

Among her works, the one I especially recommend is “Show.” This piece is extremely challenging, requiring not only the use of falsetto but also high-range chest voice.

On top of that, you need to switch between multiple vocal timbres, so in terms of difficulty it definitely ranks at S-tier.
