Eternal City (Diptych for Organ) was written by Carson Cooman in 2017 for and dedicated to Marco Lo Muscio. While the inspiration came from a visit to Rome, Italy, the title could also be viewed in a broader poetic sense as well.The first movement, “Mystic Prelude,” alternates a slow and richly colored refrain with alternating episodes whose free modality hints at the earliest notated medieval keyboard music. The second movement, “Fire Dance,” is fast and rhythmic with frequent modal shifts.
