John Pyke Hullah (27 June 1812 – 21 February 1884) was an English composer and teacher of music, whose promotion of vocal training is associated with the singing-class movement.Hullah was born at Worcester. He was a pupil of William Horsley from 1829, and entered the Royal Academy of Music in 1833. He wrote an opera to words by Dickens, The Village Coquettes, produced in 1836; The Barbers of Bassora in 1837; and The Outpost in 1838, the last two at Covent Garden. From 1839, when he went to Paris to investigate various systems of teaching music to large masses of people, he identified himself with Wilhem's system of the fixed "do," in contrast to the moveable "do" of the Tonic sol-fa.
