English composer. Jackson was born at Exeter on May 28th, 1730. His father, a grocer, bestowed a liberal education upon him, but, on account of the lad's strong predilection for music, was induced to place him under the care of John Silvester, the organist of Exeter Cathedral with whom he remained about two years. In 1748 he went to London, and studied under John Travers, organist of the king's chapel. Returning to Exeter, he settled there as a teacher and composer, and in 1777 was appointed subchanter, organist, lay vicar and master of the choristers of the cathedral. In 175 he published his first work. twelve songs, which became at one lighly popular. his next publication, six sonatas for the harpsichord, was a failure. His third work, six elegies for three voices, preceded by an invocation, with an accompaniment, placed him among the first composers of his day. His fourth work was another set of twelve songs, now very scarce; and his fifth work was again a set of twelve songs, all of which are now forgotten.
He next published twelve hymns, with some good remarks upon that style of composition, although his precepts were better than his practice. A set of twelve songs followed, containing some good compositions. Next came an ode to fancy, the words by Dr Warton. Twelve canzonets for two voices formed his ninth work; and one of them, Time has not thinned my flowing hair, long held a place at public and private concerts. His tenth work was eight sonatas for the harpsichord, iome of which were novel and pleasing. He composed three dramatic pieces, Lycidas (1767), The Lord of the Manor, to General Burgoyne's words (1780), and The Metamorphoses, a comic opera produced at Drury Lane in 1783, which did not succeed. In the second of these dramatic works, two airs Encompassed in an Angel's Form and When first this humble roof I knew were great favorites. His church music was published after his death by James Paddon (1820); most of it is poor, but Jackson in F was for many years popular. In 1782 he published thirty letters on various subjects, in which he severely attacked canons, and described William Byrd's Non nobis domine as containing passages not to be endured. But his anger and contempt were most strongly expressed against catches of all kinds, which he denounced as barbarous. In 1791 he put forth a pamphlet, Observations on the present state of music in London, in which he found fault with everything and everybody. He published in 1798 The Four Ages, together with essays on various subjects, a work which gives a favorable idea of his character and of his literary acquirements. Jackson also cultivated a taste for landscape painting, and imitated, not unsuccessfully, the style of his friend Gainsborough. He died on July 8th, 1803.
