[Challenging Songs with a Wide Vocal Range] S-Rank Difficulty Challenge Songs (41–50)
Resident of the EyeL’Arc〜en〜Ciel
A song that is often ranked among the most difficult to sing is “Hitomi no Jūnin.” This piece is by L’Arc〜en〜Ciel.
Their songs are generally perceived as having low, narrow vocal ranges.
However, in this track they showcase vocals that employ both extremely high and extremely low notes.
The high parts in particular are at an unparalleled level, so very few people can likely hit them.
The fact that it immediately drops back down to low notes also contributes to its high level of difficulty.
If you sing it, you’re sure to impress.
oni; demon; ogre; spirit (depending on context)Kizu
Among the works featured in this article, the song I most recommend as a top-tier challenge is Oni.
It’s the latest track by Kizu, a young visual-kei band known for their exceptional skill.
The song spans a very wide vocal range and packs in hard-rock vocal techniques to the fullest—mix voice, falsetto, and powerful low tones.
It also demands solid fundamental singing ability, so fewer than 0.5% of people would likely be able to pull it off flawlessly.
Innocent BlueOmoinotake
Omoinotake’s song “Innocent Blue,” released on October 29, 2025.
Many of you may have first heard it through its use in the commercial for “Bourbon Alfort Mini Chocolate,” right? The song’s vocal range spans from mid1D to hiD, which is quite wide for a male vocal track.
While the pitch movement is very dramatic, the BPM itself is a relaxed 118.
However, because there are many sustained high notes, the difficulty can definitely be considered A–S tier.
Tasty Beating SoundDa‑iCE
Da-iCE is a dance and vocal group known for their many challenging songs.
“Tasty Beating Sound,” released in September 2025, ranks among the most difficult of their recent tracks.
Its vocal range spans from mid1D to hiC.
It’s not just high; the lower notes go fairly deep as well, making key selection tricky, and the melody features sharp rises and falls.
The one saving grace is that, fitting its comical tone, the song uses fewer long sustained notes.
Despite its playful vibe, it’s an exceptionally difficult piece—definitely worth a challenge.
SubtitleOfisharu Higedan Dism
Official HIGE DANDism’s “Subtitle” is tough to grasp rhythmically because of the triplet feel, like “ta-ta-ta.” On top of the triplets, the song has many other challenging elements.
For example, it uses the key of G-flat major, which has six flats.
That scale isn’t often used in J-pop, so hitting the pitches accurately can be tricky.
Also, the flow from the A verse to the B section and into the chorus is so seamless that keeping track of where you are can be tough.
All the more reason that if you can pull this song off, even seasoned music lovers will be impressed!
Who am I?TK from RIN TO SHITE SIGURE
Ling tosite Sigure is a band with nationwide popularity.
TK serves as the frontman of Ling tosite Sigure, but he has also achieved great success as a solo artist.
Among TK’s songs, the one I especially recommend as a challenging piece with a particularly wide vocal range is Dare ga Tame.
The track is arranged overall in the higher register.
You might think that if it stays up high, the overall range isn’t that wide—but in this song, the peaks in the high range are extremely high.
It doesn’t quite reach whistle register, but it features a lot of very high falsetto, so both vocal height and stability are strongly required.
evening primroseNovelbright
The five-piece rock band Novelbright’s “Tsukimisou” is a song with challenging high notes.
Especially in the chorus, there are many parts where you have to sing very high notes in falsetto.
The song as a whole sits in a high register, and since you need to keep hitting high notes without much rest, it seems important to develop a singing technique that won’t strain your throat.
Rather than trying to sing it all the way through right away, it’s recommended to practice in sections—start with the first verse, then the second—and finally train to connect the entire song together.
