The Holy Hours Op.555 was composed in 2016 and is dedicated to David Heyes. Written primarily in bass clef, each piece is rhythmically charged and inventive, contrasting textures and timbres in a modern but accessible idiom, with none outstaying their welcome.

“The Holy Hours for unaccompanied double bass ranges from the explosively loud gloriousness of the opening and closing of Matins, to the mysterious sweetness of Vespers and Compline, The Holy Hours is a Sonata of seven short movements each of which is supposed to give the impression per the time of day of one of the seven church office hours.”
