It seems that at least part of the entertainment value of "Turkish" music was the perceived exoticism. The Turks were well known to the citizens of Vienna (where Mozart, Haydn, and Beethoven all worked) as military opponents, and indeed the centuries of warfare between Austria and Ottoman Empire had only started going generally in Austria's favor around the late 17th century. The differences in culture, as well as the frisson derived from the many earlier Turkish invasions, apparently gave rise to a fascination among the Viennese for all things Turkish—or even ersatz Turkish. This was part of a general trend in European arts at the time; see Turquerie.
