[Challenging Songs with a Wide Vocal Range] S-Rank Difficulty Challenge Tracks (111–120)
whistlingMr.Children
Among Mr.Children’s songs, Whistle boasts one of the widest vocal ranges.
Its highest note is hi A, and astonishingly, the lowest is low G! While that top note is a common peak in other Mr.Children tracks, the contrast with the lowest note makes this piece quite challenging.
Fortunately, the tempo itself is very relaxed, so the pitch movement isn’t too abrupt.
However, since you can’t really lower the key much, depending on your vocal range you may need to tackle the high parts on your own.

No Questionm-flo
m-flo is a music group highly acclaimed for their authentic mix of R&B and dance music.
If you’re in your late twenties to early thirties, you may well have been captivated by their sound, which rivals Western music.
Among their works, the song I especially recommend is No Question.
LISA, the vocalist with a distinctive tone, actually excels in the lower register, and her songs often feature a surprisingly wide vocal range.
This track is no exception—the span from low to high notes is broad, making it quite challenging.
DarlingMrs. GREEN APPLE
Mrs.
GREEN APPLE’s digital-only single “Darling,” their first release of 2025, is a grand ballad that makes extensive use of strings.
Ballads are, by nature, a test of a singer’s true ability, and for Motoki Omori—whose vocal prowess is exceptional—it’s the perfect stage to showcase his strengths.
The melody line leverages high-level techniques to the fullest, including a wide vocal range, natural vibrato, seamless command of mixed voice, and exquisite volume control, making it very challenging.
The difficulty is especially high in the section before the final chorus, where the pitch rises step by step.
If you’re confident in your skills, definitely give it a try.
MainstreamBE:FIRST
Vocal groups in Japan have undergone major changes.
With the addition of K-pop-like elements, there is now a much higher demand for vocal ability and dance performance than before.
The boys group that sparked this movement is BE:FIRST.
Their hit song “Mainstream” is hard-hitting, hip-hop-influenced dance music, and falsetto appears throughout.
It also features low-register rap, giving the song an impressive overall vocal range.
Give it a try!
Play The GameŌrin
The female TV personality Ourin, who’s been very active on variety shows, has recently been stepping up her work as an artist as well, frequently ranking high on the charts.
Among her tracks, the one I’d recommend as a high-note challenge is Play The Game.
It’s a piece that seems to emulate the musical style of the world-renowned British singer Dua Lipa, featuring a disco-meets-electropop vibe.
While it doesn’t have an abundance of high notes, the mixed voice that comes in toward the end of the chorus poses a fair level of difficulty.
Leave the Door OpenSilk Sonic
Silk Sonic is a duo that has gained popularity with a nostalgic sound incorporating the 1970s New Soul genre.
It’s the unit formed by Bruno Mars, who’s hugely popular in Japan as well, together with Anderson .Paak.
Among Silk Sonic’s songs, the one I especially recommend is Leave the Door Open.
It’s a soulful track characterized by its challenging vocal lines and wide vocal range.
Be sure to check it out.
Professionalism feat. HannyaAli
ALI is a band centered on funk and soul whose musicality has earned high praise from hardcore music aficionados.
If you’re into Black music, you’ve probably heard of them.
The track where they collaborate with rapper Hannya is “Professionalism feat.
Hannya.” While the range isn’t extremely wide, the repeated use of falsetto makes it more challenging than it sounds.
If you want it to come across well, try singing the mid-range with rich overtones.
