The relationship between the social and professional sides of the music profession is most evident when a striking failure in one adversely affected the other. A sadder case altogether, illustrating the negative impact that professional decline could have on social relationships, was the composer Antonio Sacchini, whose diminishing status during his last London years badly affected his once warm relations with the Charlotte Burney family. A performer whose professional and social reputation had not significantly diminished at the time of his death was Johann Peter Salomon, the celebrated violinist and impresario. This chapter provides a reassessment of Salomon's uneven career in London during the 1780s. In the case of Salomon, Susan Burney's letters suggest that, recognizing his public career prospects to be on the wane in London, he attempted to make use of his personal relationship with the family to achieve his as yet unfulfilled ambitions.
