Interpretation notes:

• The hymn uses an undulating melody, stepwise passages, repeated notes in measure 9, repeated E-flat notes in the refrain, and syncopated rhythms throughout. 

• The word 'you' in measure 15 is set to a longer note value. 

• These features shape how the text is presented in the melody.
