Pianist Simone Dinnerstein chose the title "Undersong," an archaic term meaning "refrain", which can be found both in the individual pieces (Schumann's Arabesque, and Kreisleriana; Couperin's Les Barricade Mysterieuses), and throughout the entire album.

"All of the music on this album consists of musical forms that have a refrain. Glass, Schumann, Couperin and Satie constantly revisit the same material in these pieces, worrying at it, shifting it to different harmonies and into different rhythmic shapes. Working with this music in the fall of 2020 was a constant reminder that in my afternoon walk in Green-wood Cemetery, I was quite literally treading a familiar path every day, a path that nonetheless had changed almost imperceptibly every time I left the house." - Dinnerstein
