Symphony no. 36 "Linz" in C major, K. 425

Returning from Salzburg to Vienna in the autumn of 1783, Mozart stopped at Linz as the guest of Count Johann Joseph Thun and found a concert already arranged for him. He wrote to his father on 31 October that he had not a single symphony with him and was writing one head over heels, to be given on 4 November — about four days' work. It opens with the first slow introduction in any of his symphonies, a device taken from Haydn, and the trumpets and drums that follow carry a festive weight suited to the occasion that produced it.
