[Challenging Songs with a Wide Vocal Range] S-Rank Difficulty Challenge Songs (41–50)
Kaiju no Hanabuta (Monster’s Flower Song)Vaundy
Singer-songwriter Vaundy, who enjoys immense support from teens and people in their twenties, is a multi-talented artist who creates everything from catchy tunes to highly demanding pieces.
Among his works, the one I especially recommend for its exceptionally wide vocal range is Kaiju no Hanauta.
Its chorus features striking falsetto and makes extensive use of mixed (middle) voice.
While the chorus may become somewhat easier to sing if you use a non-breathy falsetto that doesn’t clamp the throat, it’s still very challenging—undoubtedly an S-rank song.

AliensKirinji
Aliens, one of Kirinji’s signature songs.
It’s frequently featured in media like commercials in Japan, so many younger listeners may know it as well.
Despite its languid, world-weary vibe—which often leads to misunderstandings—the song actually spans a very wide vocal range.
The low notes are especially challenging, with the verses and pre-choruses staying consistently in the lower register.
It’s not a song you can master just by having a high voice, so if you’re confident in your lower range, definitely give it a try.
crimsonX JAPAN
When people are asked to name a song with a wide vocal range, many probably think of Kurenai.
This song is a masterpiece by X JAPAN, one of Japan’s most iconic visual kei rock bands.
The vocalist, Toshi, has a much higher voice compared to many other singers.
While a high voice alone doesn’t necessarily mean a wide range, Toshi can also produce solid low notes, and most of their songs span a broad range.
Even among them, Kurenai is exceptional.
It also requires mixed voice technique, so if you have a relatively high and wide vocal range, definitely give it a try.
OCTAVEOCTPATH
OCTPATH is an eight-member boy group under Yoshimoto Kogyo.
They’re a group whose performances hold up even compared to K-pop idols, and their popularity has been soaring since 2024.
Among their songs, the one I especially recommend is OCTAVE.
It’s hip-hop flavored dance music with frequent forays into the high register.
The toughest part of the song is the tail end of the C section.
There’s a long, sustained mixed-voice note there, and because it’s quite high, only a limited number of male singers will be able to pull it off.
Ordinary daysmilet
Milet’s “Ordinary days,” with its distinctive, addictive vocal timbre, is a song I’d love to see women who are confident singers try.
It’s quite challenging because the chorus features a series of sustained high falsetto notes, and not just in the chorus—there are many phrases throughout that leap suddenly from low to high notes.
You’ll want to lock in the pitch carefully to avoid going off-key.
If you have a piano or another instrument at home, practice by checking each pitch one by one, and you’ll be able to nail it at karaoke!
one difficultyPenthouse
Penthouse is a six-member band featuring twin vocals.
They’ve carved out a unique genre they call city soul, and their exceptional musicianship has earned them high acclaim within the industry.
Among their songs, the one I especially recommend as a particularly challenging piece is Ichinan.
It follows what’s commonly known as the Marusa progression and maintains a jazzy atmosphere throughout.
There’s plenty of falsetto, but surprisingly a lot of low notes as well, so if it feels too difficult, try singing it as a male-female duet.
Headless Angeljoōbachi
Queen Bee’s masterpiece “Headless Angel.” When you think of Queen Bee, you probably picture those striking vocals that incorporate an unusually high falsetto, right? This song is exactly one of those, featuring many phrases where you need to beware of the soaring high notes.
Among them, the chorus stands out as overwhelmingly difficult.
After a B-melody grounded in the mid-to-low range, you have to shoot the pitch up suddenly and sing the chorus in a very high falsetto—and keeping the pitch under control here is incredibly tough! On top of that, the falsetto section is long, so strong endurance is also required.
