The present Sonata da Chiesa is fashioned after the 17th century model with its many short movements in contrasting tempi. The Sonata opens with a brooding recitative played on the viola in its lowest register. The organ enters with an allegro which introduces a dotted rhythm subsequently heard in both instruments. After an extended interplay the movement ends quietly, The hushed second movement is cast in the form of a baroque trio sonata movement. The two high voices (the right hand of the organ and the muted viola) play in the same register. The left hand of the organ provides a 4 note ostinato bass part. The third movment opens with an urgent toccata on full organ which alternates with soft high harmonics on the viola. This is followed by a serene and graceful aria. The dashing final movement, a jaunty and jocose rondo, drives to a brilliant conclusion. The viola part is edited by Patricia McCarty. Total duration with pauses: 16 minutes.
