Divertimento in B-flat major: Zweite Lodronische Nachtmusik KV 287 (271b, 271 H), 2 Horns, 2 Violins, Viola and Bass, Score

Mozart composed his two  Lodron Serenades for open-air performances on the name day of Countess Antonia Lodron in June 1776 and 1777. Their bright  al fresco character is immediately recognisable. Alfred Einstein consideredthese two divertimentos to be  among the purest, gayest, most satisfying, and most perfect that ever assumed musical form .
For both works Mozart chose an ensemble of two horns, two violins, viola and bass instruments. However,the second Lodron Serenade, the Divertimento in B-flat major K. 287, stands out from this sextet format by assigning a remarkably virtuosic solo role to the first violin, from the richly diverse opening movement to the finale withits almost ironic recitative and an exhilarating passage on the folk song  D'Bäurin hat d'Katz verlorn . Mozart himself played first violin in the 1777 performance. Later he wrote,  They all opened their eyes! I played as though Iwere the finest fiddler in all Europe .
