Another branch of concerted music high in favour in Mozart's day was the so-called "Harmoniemusik," written exclusively for wind instruments, and for performance at table or as serenades. Families of rank frequently retained the services of a band for "Harmoniemusik" instead of a complete orchestra.[28] The Emperor Joseph selected eight distinguished virtuosi[29] for the Imperial "Harmonie," who played during meals, especially when these took place in the imperial pleasure-gardens. The performances included operatic arrangements as well as pieces composed expressly for this object.[30] Reichardt dwells on the enjoyment afforded him in 1783 by the Harmoniemusik of the Emperor and the Archduke Maximilian. "Tone, delivery, everything was pure and harmonious; some movements by Mozart were lovely; but unluckily nothing of Haydn's was performed."[31] First-class taverns supported their own "Harmonie" bands, in order that the guests might not be deprived of this favourite accompaniment to their meals.[32] Besides the great serenades, intended for public performance, the old custom was still practised of writing "Standchen,"[33] for performance under the window of the person who was to be thus celebrated; and the general desire that such pieces should be new and original provided composers with almost constant employment on them.[34] Wind instruments were most in vogue for this "night-music." The instruments were usually limited to six--two clarinets, two horns, and two bassoons, strengthened {SERENADES FOR WIND INSTRUMENTS.} (25) sometimes by two oboes. Such eight-part harmonies sufficed both the Emperor and the Elector of Cologne as table-music and for serenades; and at a court festival at Berlin in 1791 the music during the banquet was thus appointed.[35] The "Standchen," in "Cosi fan Tutte" (21), and the table-music, in the second finale of "Don Giovanni," are imitations of reality. Mozart did not neglect the opportunities thus afforded him of making himself known during his residence in Vienna. He writes to his father (November 3, 1781):--
