In March 1799 John White was 20 years old and already an experienced professional violinist and cellist. He kept a detailed account book between March 1799 and March 1800 that provides much information about the economic and professional life of a young musician at the very end of the eighteenth century. White had showed early musical promise, and when he was 15 he attracted the patronage of the future Lord Harewood, who enabled him to take lessons from leading musical figures and appointed him as his director of music. White lived at Harewood House, near Leeds, but he spent some months of the London season each year with the Harewood family in their house in Hanover Square. The accounts show how White earned money in London by playing at private and public concerts and deputising at almost every place of musical entertainment in the capital. In Yorkshire he led orchestras in concerts and oratorio performances, took on pupils and visited Scarborough. White’s meticulous lists of his income and expenditure, from an expensive violin, a harp and harp lessons to silk stockings, waistcoats and hair ribbon, paint a fascinating picture of a young man making his way in the musical profession.
