John, one of the most celebrated pianoforte-players of his age. He was born in the year 1782, in Dublin, where his father held an appointment as violinist at the Theatre Royal. He learned the principles of pianoforte-playing from his grandfather, who was an organist, but displayed little industry or zeal in the cultivation of his art till the removal of the family to London in 1798, when he was placed under the tuition of Clementi. He became the favourite pupil of this great master, and accompanied him to the Continent in 1802. He made a brilliant debut in Paris, enjoyed similar success at Vienna, and thence proceeded with Clementi to Russia, where he spent the greater part of his life. He died at Moscow in 1837. The peculiar characteristic of Field's playing was its extreme delicacy, precision, and gracefulness. The musical compositions of Field, consisting of seven concertos, a quintetto, sonatas, variations, fantasias, &c., display those excellences for which his own performance was distinguished.
