At the beginning of February 1794, Haydn went to London for his second stay in England. The Symphony in E flat major Hob.I: 99 was already finished by this time, and was already premiered on February 10. The public and the press were enthusiastic, which was confirmed by a review the next day: "This is one of the greatest artistic events we have ever attended [...] - It was greeted with thunderous applause." An exceptional work therefore, in all fields, if only by the introduction, for the first time, of clarinets in a symphony by Haydn, but also by the delicacy of the contrapuntal realization of the final movement. Anyone wishing to learn more about this symphony will be keen to acquire this inexpensive study edition - accompanied by reliable texts devoted to the birth of the work, its sources and the edition itself, and including the impeccable musical text from the Complete Edition of Haydn's Works.
