Interpretation notes:

• The hymn uses a smooth, mostly stepwise melodic line. 

• The opening phrase begins with ascending thirds, and the final verse lines rise higher with more leaps. 

• One verse phrase uses only three notes and repeated Cs, creating a narrow melodic range. 

• The refrain repeats the text 'into my heart,' and the final line rises to a high D before resolving to middle C.
