Interpretation notes:

• The hymn follows an ABAC form, with the first and third lines sharing the same melody and the second and fourth lines using different material. 

• The opening melody includes a descent by sixth followed by an ascent by fifth. 

• In the second line, the alto ascends chromatically, leading to a secondary dominant in D major. 

• The soprano ends on the highest note in the final section.
