Interpretation notes:

• The hymn is in 3/4 time, and the downbeats help highlight key words such as 'the longer I serve Him the sweeter He grows.' 

• In the chorus, repeated notes set phrases like 'longer I serve,' 'more that I love,' and 'day is like heaven.' 

• The repeated vocal lines create forward motion and lead into the next measure.
