"Murillo's Lesson", also known as "Marilla's Lesson", "Morella's Lesson" or "Morelli's Lesson" is an American march, hymn tune and air in G major, C major or Eb major. The parts are played AABB or AAB in The Sacred Harp. The melody can be found in a number of early 19th century American instrumental tutors, where it seems to have been a staple of the fife repertoire and in period march collections. It appears as early as the Thomas Nixon fife manuscript (as "Morelli's Lesson"), dated c. 1776-78, from the period of the American Revolution. It can also be found adapted for use in The Sacred Harp hymnal, where the indicated tune was "Morelli," or "Lesson by Morelli." It was adapted by fiddlers, particularly from Alabama and contiguous states, as an air or march. The song called "Murillo's Lesson" can be found in the 1844 Sacred Harp and the 1848 Sacred Melodeon 'fa-so-la' hymnals. Lyrics were derived in part from a poem entitled "Columbia" (AKA "Star of Columbia") by Timothy Dwight (1752-1817), printed in 1794. Dwight was one of the “Hartford Wits,” a group of Connecticut men associated with literary work during and after the American Revolution. He would go on to become president of Yale College, but was a young man when he wrote his lyric “Columbia” in 1778, when he was a chaplain in George Washington’s Continental Army. The first strain is shared with "The Colosseum", "Harlequin Hornpipe" and "Harlequin Gambols". "Bonaparte Crossing the Rhine" is a distanced version of this strain. It was printed in Howe's Complete Preceptor for the Accordeon (1843) and The Sacred Harp.
