Although the melody is based on a traditional mode of Japanese court music, it is composed in a mixed style derived from Western hymns.
[3] Eckert rearranged the existing anthem per the Gregorian mode for Western instrumentation, making suitable modifications for playability at sea, including a four-part vocal arrangement.
In 1897, he was invited to compose a special song, which he titled Kanashimi no kiwami, for the funeral of Empress Dowager Eishō (widow of Emperor Kōmei).
Eckert returned to Germany in 1899 due to ill health, and obtained a posting at the Berlin Philharmonic, but was soon appointed music director to Kaiser Wilhelm II.
However, his stay in Germany was short, and soon after his health had improved, he accepted an invitation extended by the Korean Empire to build a court orchestra and to train musicians in European musical instruments and techniques.
His situation was complicated by renewed ill health, and the outbreak of World War I and, in 1916, he resigned as conductor of his orchestra in favor of his first flautist, whom he had trained as his successor.
