The Symphony no. 77 in Bb, Hob. 1/77, is a work by Joseph Haydn completed in 1782. The finale movement here is by most agreed to be the Haydn's first use of the sonata rondo form. In 1782, almost a decade before Haydn composed the first of his famous London symphonies, he composed a trio of symphonies – 76, 77 and 78 – for a trip to London which fell through. Haydn wrote the following to his Paris music publisher Boyer, who wanted exclusive rights over them, but Haydn refused. It is not known how much Haydn knew of the tastes of English audiences, but the three symphonies do possess a polish and style typical of London composers such as Johann Christian Bach and Carl Friedrich Abel. The symphony is scored for flute, two oboes, two bassoons, two horns and strings and it is in four movements.
