[Challenging Songs with a Wide Vocal Range] S-Rank Difficulty Challenge Songs (31–40)
Wolverine Nenzutto mayonaka de ii no ni.

They captivate the scene with their wide-ranging musicality, but this work is characterized by a focus on emotional intensity.
At first listen, it may feel somewhat gentle in mood; however, the vocal range here is surprisingly broad, with high falsetto passages appearing repeatedly.
In addition, since the songs are built around the mid-to-high register, they also demand considerable vocal stamina.
If you experience headaches when singing pieces like these, try keeping your chin slightly tucked while you sing.
Fake Love and HighballLET ME KNOW

Right now, the band LET ME KNOW is gaining popularity in South Korea.
Their sound blends indie rock with new wave, and they’re known not only in their home country of Japan, but also in cities like South Korea, Taiwan, and Hong Kong.
Among their songs, the one I especially recommend is “False Love and Highball.” While the track features prominent mid-to-high registers, a solid falsetto also appears in the chorus.
The vocal range isn’t outrageously wide, but there are a lot of long sustained notes, so you might run out of breath during the falsetto parts.
Taking that into account, it’s definitely a challenging song.
unravelAdo

The song “unravel” by TK from Ling tosite sigure.
Although it was released in 2014, it drew attention when Ado covered it in 2023 and saw a revival hit in 2024.
The piece is known for having a very wide vocal range.
It contains many passages in the high register that demand a stable falsetto, and beyond that, it even features screams akin to death growls partway through.
Breathing is also challenging, making it a song that requires strong fundamental vocal technique.
StarmineDa-iCE

Da-iCE’s “Starmine” feels great with its piercing high notes.
This song seems especially hard to nail in the parts sung by Sota Hanamura, known for his “four-octave” vocals.
It also uses a lot of “ganari,” a growling, raspy singing technique, so if you learn that while taking care not to strain your throat, you’ll be closer to the original sound.
Singing while doing some light dance moves will make it look even cooler, so if you’re up for it, why not check out videos on YouTube and give it a try?
Blooming in the mudUorupisukātā

Wolpis Carter is a male singer whose voice is so clear and beautiful it could be mistaken for a woman’s.
He’s known as a “guy who wants to hit high notes,” and this song is his specialty! The melody climbs even higher toward the end, so unless you’re comfortable with high tones from the start, it’s tough to sing in the original key.
The last chorus might give you a headache… But when a song is this high, it actually feels downright beautiful.
I personally love high-note songs, and belting them out feels amazing.
The overall range is quite wide, from G#3 to F5, so be careful not to strain your throat on the low notes.
Lift your facial muscles from the beginning and sing it through to the end!

over the topMiyamoto Hiroji

Elephant Kashimashi’s frontman, Hiroji Miyamoto.
Lately he’s been very active as a solo artist as well, and through collaborations he’s become known among younger generations.
His new song “over the top” is one of the most challenging pieces in his catalog.
The song spans a very wide vocal range, and all the high phrases are delivered powerfully, demanding considerable vocal stamina and lung capacity.
On top of that, it features a number of subtly delicate techniques, making it extremely difficult overall.
dizzyAdo

Ado’s new song “Kurakura.” Released in October 2023, it opens with a King Gnu-like vibe, while the chorus resembles Official HIGE DANDism’s “Mixed Nuts,” and the entire track is wrapped in a very dazzling atmosphere.
A challenging aspect of this song is the frequent use of low falsetto.
On top of that, the end of the chorus needs to be sung with a voice close to mixed voice, demanding the ability to switch rapidly between high range, falsetto, and chest voice.
