Fantasy on “Valmai” (1999) was written for and is dedicated to organist Huw Lewis. The work was commissioned by H. Hubert Benckler The composition is based on Lewis’s hymn tune Valmai, a setting of the text What a Friend We Have in Jesus. This work explores tune both in its direct form (firstly in a chorale prelude-style, followed by a canonic setting) as well as through melodies derived from transformations on Valmai by the use of magic squares.
