This is a reprint of the official scorebook "Official Scorebook 坂本龍一 /05" published in 2005 under the supervision of 坂本龍一. The original book had been out of stock for a long time, and many fans had been hoping for its re-release. Therefore, we have now reproduced the book in a form that is as faithful to the original as possible, not only in content but also in design.

The original of this music book is "/05" (released in 2005), a self-cover album featuring piano performances by 坂本龍一.

The "Official Scorebook 坂本龍一 /05 Reprint Edition" corresponding to this album "/05" contains 13 songs.

The album includes "Tibetan Dance" arranged for piano, "A Flower is not a Flower," a solo piano performance of a piece written for erhu player Kenny Wen, "Amore," which 坂本龍一 says is arranged as a "meditative piece," and "The Huge Hit. Amore," which he arranged as a "meditative song," the hit commercial song "Energy Flow," "Aqua," which he describes as "one or two of the simplest songs," "The Last Emperor," a piano arrangement of the theme song from the movie "The Last Emperor," and a four-piano reconstruction of a song from YMO's "BGM" album. Happy End", a piano arrangement of the theme song from YMO's "BGM" album, "Thousand Knives", a piano version of a song from his first solo album, "Fountain", a song created for an installation by Takeharu Kogiri, a contemporary artist, "The Sheltering Sky", the theme song from the movie "The Sheltering Sky", and a piano version of a song from the movie "The Last Emperor", and a piano arrangement of a song from the movie "BGM". The Sheltering Sky", "Lost Theme", one of the theme songs for the movie "FEMME FATALE", "Shining Boy & Little Randy", the theme song for the movie "The Boy Who Became a Star: Shining Boy & Little Randy", and the theme song for the album "BTTB". The score for "Reversing," which was included as a bonus track on the international edition of the album "BTTB," is included in the book.

One of the main features of this collection is that 坂本龍一 himself explains the songs and gives tips on how to play them. In addition, a long interview is included. The content of the interview is extremely valuable and goes deep into music theory as well.

In addition, the original official scorebook was produced by 坂本龍一, who was also deeply involved in the choice of paper and design. The late Hideki Nakajima (Nakajima Design), who also worked on the album jackets of 坂本龍一, was the art director of the project. The paper was chosen for its eye-friendly hues, and the printing was done with a careful attention to detail, with blurring and blurriness mixed in. The reissued version retains these details, but has been given FSC certification for the purpose of forest protection. This is of course out of sympathy for the forest conservation organization "more trees," which he founded. Therefore, we would like to ask for your understanding that some of the forms and other parts of the book may differ from the original.

The album "/05" is not just a collection of piano works, but a collection of piano arrangements filled with ambitious creativity. This collection can be called another "/05" that visibly expresses that creativity. We hope that many people will play this album.
