The difficulty varies greatly depending on the arrangement and performance approach, but the more complex the arrangement, the cooler it tends to be.

This is a grand ballad by Ado, who’s blazing down the unstoppable path of stardom, and it also serves as the theme song for the film ONE PIECE FILM RED.

When played with just the piano, it sounds surprisingly tranquil.

The extremely simple low notes resonate with a crisp punch, resulting in a truly magnificent sound.

It’s a refined arrangement that shines whether you play it fast or slow—savor it to the fullest.

Wataridori, released in 2015 as the major-label debut single of the rock band [Alexandros].

The song has been featured in beer and car commercials as well as the BGM for popular attractions, and these days it seems to be a staple at school sports days and athletic festivals.

When trying to recreate its exhilarating, fast-paced sound—so well-suited to dynamic visuals and events—on the piano, the difficulty inevitably rises.

It’s ideal to maintain a steady tempo in the accompaniment to convey a positive energy, while allowing the melody to be played freely in broad phrases.

YOASOBI’s “Idol,” used as the opening theme for the TV anime Oshi no Ko, became a global sensation, ranking high not only on domestic music charts but also on international ones.

The track is packed with addictive elements—programmed sounds, sound effects, and ikura’s rap.

Because it’s up-tempo and features many complex key changes, it’s quite a challenge to reproduce on the piano! However, if you can play it with a solid groove and sharp articulation, it will undoubtedly level up your piano performance.

Give it a try!

Composed around the themes of human connections and bonds, it blends simplicity with dynamic power.

The difficulty of performing this piece on piano varies greatly depending on the arrangement.

An arrangement that maximizes the piano’s expressive potential demands advanced technique, while a gentle, music-box-like arrangement requires a delicate touch to control the sound.

With Sheet Music: I’m a mess / MY FIRST STORY (Piano Solo Intermediate–Advanced) [Piano Arrangement Sheet Music]
I'm a messMY FIRST STORY

The popular rock band MY FIRST STORY, known as “MaiFasu,” released “I’m a mess” as the B-side to their single “Kokuhaku.” Sparked by a surge of TikTok videos using the track in a short period, the song quickly climbed various charts and became a massive hit, now standing as one of the band’s signature tunes.

While rooted in rock, it also carries a certain calm atmosphere—that balance is part of its appeal.

To avoid a performance that’s merely loud and intense, make full use of dynamic changes in the piano tone to elevate the performance to a higher level.

unravelTK from RIN TO SHITE SIGURE

The single “unravel,” released by TK from Ling tosite sigure, the vocalist of the rock band Ling tosite sigure, was used as the opening theme for the anime Tokyo Ghoul.

Beneath its complex and sophisticated melodic lines, the rhythm is constantly subdivided, so solid technique is required to play it well on piano.

However, if you omit this pulsating subdivision, the piece feels lacking, so it’s worth practicing thoroughly to master it.

Along with finger technique, refine your expressive abilities to recreate its unique sound world, and aim for a highly polished performance!
