Henry David Leslie was born in London, June 18, 1822, and in his sixteenth year began his musical studies with Charles Lucas, a famous violoncellist and for a long time principal of the Royal Academy of Music. Like his master, Leslie played the violoncello several years in the concerts of the Sacred Harmonic Society, subsequently becoming its conductor,--a position which he held until 1861. In 1855 he organized the famous Leslie choir of one hundred voices, which took the first prize at the international competition of 1878 in Paris. In 1863 he was chosen conductor of the Herefordshire Philharmonic Society, and in the following year became principal of the National College of Music. In 1874 he was appointed conductor of the Guild of Amateur Musicians in London. He has been a prolific and very popular composer, among his works being the following: Te Deum and Jubilate in D (1846); symphony in F (1847); anthem, "Let God arise" (1849); overture, "The Templar" (1852); oratorio, "Immanuel" (1853); operetta, "Romance, or Bold Dick Turpin" (1857); oratorio, "Judith," written for the Birmingham Festival (1858); cantata, "Holyrood" (1860); cantata, "The Daughter of the Isles" (1861); and the opera "Ida" (1864). In addition to these he has written a large number of songs, anthems, part songs, madrigals, and piano pieces, besides music for his choir. Holyrood. "Holyrood" was written in 1861, and was first produced in February of that year at St. James's Hall, London. Leslie's collaborator was the accomplished scholar Chorley, who has certainly prepared one of the most refined and attractive librettos ever furnished a composer. The story represents an episode during the period of Queen Mary's innocent life, overshadowed in the close by the dismal prophecy of the terrible fate so rapidly approaching her. The characters are Queen Mary (soprano), Mary Beatoun (Beton), her maid of honor (contralto); Rizzio, the ill-fated minstrel (tenor); and John Knox (bass). The scene is laid in a court of the palace of Holyrood, and introduces a coterie of the court ladies and gentlemen engaged in one of those joyous revels of which Mary was so fond. In the midst of the pleasantry, however, the Queen moves pensively about, overcome with sadness, as if her thoughts were far away. Her favorite maid tries in vain to rouse her from her melancholy with a Scotch ballad. The minstrel Rizzio is then urged to try his skill. He takes his lute and sings an Italian canzonet which has the desired effect. The sensuous music of the South diverts her. She expresses her delight, and seizing his lute sings her new joy in a French romance. It is interrupted by a Puritan psalm of warning heard outside. The revellers seek to drown it; but it grows in power, and only ceases when the leader, John Knox, enters with stern and forbidding countenance. The Queen is angry at first, but bids him welcome provided his mission is a kindly one. He answers with a warning.
