The Sonata “Ad Patres” by Lithuanian composer Bronius Kutavičius (b. 1932) borrows its title from a series of paintings by fellow countryman Mikalojus Konstantinas Čiurlionis (1875-1911). The music explores how simple repeating patterns create both drones and resulting melodies.
Originally written for two organists in 1991, the piece has since been transcribed for organ solo by Jūratė Landsbergytė (b. 1955). As a solo piece, a performance becomes more an interplay between the control of two hands instead of the separate points-of-view of two players.
