John Walsh was an English music publisher of Irish descent, established off the Strand, London, by c. 1690. He was appointed musical instrument-maker-in-ordinary to the king in 1692.
Walsh began publishing music in 1695, at which time he had few rivals in the trade. The firm established by John Playford in 1647 was in decline under his son Henry, and Thomas Cross was more involved with engraving than publishing. Walsh took advantage of this situation, and soon his firm was printing engraved music on a scale previously unknown in England. In addition to English composers, he published a good deal of music by foreign composers, which he often copied from Dutch editions (Kidson et al. 2001a).
