Mack Wilberg's How Can I Keep From Singing for SATB choir and Piano. Wilberg's arrangement of Robert Lowry's text and melody is a beautifully reflective take on the well-known hymn. Simple vocal lines are enhanced by a gently flowing accompaniment rich in suspensions and harmonic interest. This part can be played on the Piano or by the unusual combination of Flutes Cors Anglais Harp and Strings.
