Music is the shorthand of emotion. (Leo Tolstoy, 19th-20th century Russian writer)
Why do dramatic movie and TV shows have carefully written music backgrounds? Composers and conductors are hired to enhance the show with music that will play to the emotion, subtly perhaps, but it is purposely designed to highlight the desired emotional response. Without music much of movie life and, more importantly, real life would be bleak and unfeeling.
David also ordered . . . a choir of Levites who were singers and musicians to sing joyful songs to the accompaniment of harps, lyres, and cymbals. (1 Chronicles 15:16)
