Challenging Mr.Children Songs | A Must-See for Confident Singers! A Collection of Mr.Children’s Difficult Tracks (1–10)
Tomorrow never knowsMr.Children

Mr.
Children has many difficult songs, but among those, the highly well-known “Tomorrow never knows” is the one I especially recommend.
The main challenge lies in the final chorus.
Due to a key change, the key modulates up by two semitones, and since the original range is from mid1 F to hi B, there isn’t much room to lower or raise the key.
It’s fundamentally a song that demands a wide vocal range from the singer.
Truly worthy of being called a difficult piece.
If you’re confident in your vocal range and pitch control, give it a try.
walnutMr.Children

The classic song “Kurumi,” which gained popularity for its heartrending lyrics, is composed as a slow ballad—one of the patterns Mr.
Children excels at.
Because the tempo is that of a slow ballad, it tends to be easy to sing.
The vocal range is fairly wide at mid1E to hiF, with the hiF appearing after the key change.
Due to the nature of a slow ballad, it doesn’t require a great deal of vocal power, but since the arrangement is relatively sparse, it’s harder to mask imperfections, so practice is a must.
Marshmallow dayMr.Children

Among Mr.
Children’s songs, “Marshmallow day” is one of the most challenging.
Its vocal range is quite wide, from mid1C to hiF.
While the high notes tend to draw attention, the mid1C section is actually quite tough, and the A melody sits very low with little room to lower the key, making it tricky to adjust.
If you’re good at high notes but struggle with low ones, one option is to sing the A melody an octave higher.
Since falsetto appears in the bridge, be mindful not to shout too much in the choruses beforehand so your voice doesn’t get worn out.

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.
CENTER OF UNIVERSEMr.Children

CENTER OF UNIVERSE is a slow-tempo rock track that’s very popular among fans.
Its vocal range is wide, from mid1C to hiA, with a notably low lower register.
The chorus sits at the lowest part, but since the song itself feels bright, you need to project well even in the low range.
The rapid-fire section at the end of the chorus demands endurance in the throat, so be careful not to over-open your throat in the low notes and strain yourself.
While many Mr.
Children songs are known for their high melodies, this one is challenging for its low notes, so if you have a deeper voice, definitely give it a try.
For Whom the Alchemist ExistsMr.Children

As a work with a strong message, “Tagatame” enjoys solid support from hardcore fans.
Its vocal range is quite wide, spanning mid1C to hiB, and because the lowest note is mid1C, there isn’t much room to lower the key.
It also features a hi A# shout, so a powerful high-register delivery is required.
In addition, the lyrics are emotional, so a vocally expressive performance is needed; even though there’s no falsetto, overall it can be considered a very challenging piece.
#2601Mr.Children

When it comes to Mr.
Children, their orthodox J-pop sound is what usually stands out, but they also have some hardcore tracks.
Among those, the one I especially recommend as a particularly difficult song is “#2601.” It spans a very wide range from mid1 C-sharp to high A-sharp, and on top of that, most of the chorus sits on high A-sharp.
What’s more, it’s not sung in falsetto, but in full-voice shouts, so unless your throat is exceptionally strong, it will be hard to pull off.
