Interpretation notes:

• The hymn is in a major key and uses a march-like 4/4 rhythm. 

• Quarter notes appear frequently, and many phrases begin with an upward fourth. 

• The melody uses disjunct motion in several places, including two fifth leaps in the third system and a stepwise ascent after the first fifth leap. 

• The repeated phrase 'Stand up' matches the hymn’s text and reinforces its call to action.
