George Frideric Handel was the house composer at Cannons from August 1717 until February 1719. The Chandos Anthems and other important works by Handel were conceived, written or first performed at Cannons.
Cannons was a large house in Middlesex, the seat of James Brydges, 1st Duke of Chandos who was a patron of Handel. The duke, a flute player, had a private orchestra, consisting of 24 instrumentalists.Johann Christoph Pepusch was the Master of Music at Cannons from 1716 and he saw the size of the musical establishment at first expand and then decline in the 1720s in response to Brydges' losses in the South Sea Bubble, a financial crash which took place in 1720.
Handel settled in England in 1712, but appears not to have maintained his own household in London until 1723. He attracted the patronage of noblemen such as Richard Boyle, 3rd Earl of Burlington, and he was based at Burlington House before becoming Cannons' resident composer from 1717 to 1718. It has been suggested that the move to Cannons was related to the fact that in 1717 there was reduced demand for his services in central London because operatic productions were experiencing a temporary downturn. At the end of Handel's stay at Cannons, the Duke and his friends helped him establish a new opera company in London, the so-called Royal Academy of Music.
Handel wrote church music for performance at Cannons, the Chandos Te Deum and the Chandos Anthems (settings of texts from the psalms for use in the Anglican liturgy). While Handel was at Cannons, the ducal chapel was still being constructed (it was finished in 1720). The church music was performed at the parish church (St Lawrence, Whitchurch). The church reopened in 1716 after the Duke had reconstructed the building to his baroque taste. St Lawrence still contains artwork by Louis Laguerre and Bellucci (who also worked on the decorative scheme of the house). At the east end of the church is the organ used by Handel. Modernised over the years, it was restored in 1994 using the surviving parts of the original 1716 single-manual organ as the reference point.
