Interpretation notes:

• The melody begins with several intervallic leaps in the opening line, including a minor seventh from 'may' to 'be.' 

• In the chorus, the melody stays in the upper soprano register, around D-flat 5, E-flat 5, and F5. 

• The climax occurs in the third line of the chorus, 'Tho billows roll, He keeps my soul.' 

• These features support the hymn’s theme of trusting in God.
