This is a collection of arrangements of patriotic songs, hymns, and gospel music, dedicated to Dell Dickins Scoper. Among these, 'Amazing Grace' and 'The Battle Hymn of the Republic' are perhaps the only ones familiar to Japanese people. The other pieces are strongly religious in nature, primarily sung in Christian gatherings. It is well-known that Christianity continues to hold significant influence in the United States, a country where multiple ethnicities and religions coexist. Societal conditions are reflected in the music industry, and in the U.S., music for Christian ministry constitutes a major genre. Although opportunities for their introduction in Japan are scarce, an enormous volume of sheet music is published for piano solo, organ solo, and piano and organ duets (sometimes adaptable for two pianos). Engaging with these works can aid in understanding the core of American culture. Rocherolle's collection, too, offers valuable insights when approached, transcending differences in faith and customs. The arrangements, which combine reverence, delicacy, and grandeur, are also rich in pure musical appeal. The difficulty level is somewhat high, requiring a technique comparable to Czerny 40.
