The message of the lyrics to "let nothing disturb you" is reflected in the fluid rhythmic pacing, freely alternating between measures of 4/4 and 3/4, and two salient harmonic elements: the smooth voice-leading of the common-tone chromaticism and the use of the "softer" sounding subtonic chord as a dominant substitute. Accompanied by piano, this can work as a simple, beautiful SATB anthem or as a soprano or tenor solo. Pay special attention to the varied dynamic markings that capture the beauty of this comforting yet stirring text. In the grand sections, cue-sized notes provide optional divisi for larger choirs, but can be omitted for smaller choirs while still maintaining the full, dramatic sound.
