A Digital Book About Music Analysis

I'd like to write and release a book titled "How He Composed 'Merry Christmas Mr. Lawrence" (彼はどうやって「戦場のメリークリスマス」を作曲したか) in Japanese and English one day. Analyzing music in print media has its limitations. I believe some text media with the ability to include videos and audio files such as digital books would be more suitable for this project.
