(b Oxford, bap. 15 April 1757; d Boston, MA, 18 Nov 1822). English-American composer, teacher and editor. He reportedly studied under Nares at the Chapel Royal, and while in London he taught privately, wrote a number of sacred and secular compositions and published a Treatise on Practical Thoroughbass (1785). St Andrews University granted him a doctorate in music (1791), which probably was an honorary award.
By 1797 he was in New Brunswick, New Jersey; there, while professor of music at a private academy, he presented concerts of popular and art music which received favourable attention throughout the state. He moved to New York in 1801 and remained there, teaching and giving concerts, until 1812 when he moved to Boston. Jackson played a prominent part in that city’s musical life as a teacher, composer, conductor, organist, music seller and consultant to the newly formed Handel and Haydn Society.
Jackson’s reputation rested mainly on his skills as an organist and teacher, but he also wrote nearly 100 compositions. He was essentially a conservative composer, making much use of figured bass and of fugal techniques. His keyboard pieces do not reflect his own apparent proficiency as a performer, but often are clearly didactic. His few surviving hymns and chant settings are stolidly harmonized in textbook style, but the settings of Dr. Watt’s Divine Songs are tuneful and show a degree of sophistication in their use of chromatic inflection and broad melodic curves not usual in contemporary settings of Watts.
