The concert on 19 December 1886, with its programme drawn appropriately from the Vienna-based composers Beethoven, Heuberger and Fuchs, was Hans Richter's one hundredth Philharmonic concert. Just before it took place, he wrote a letter to the orchestra which shows the excellent relationship between the conductor and his men. He referred to the famous Viennese brothers Johann and Josef Schrammel, who by 1886 had a tavern quartet of two violins, guitar and clarinet and had added the word Schrammelmusik to Vienna's musical language. They had begun as a trio in 1878 and in 1884 wrote a Hans Richter March. They mainly played old Austrian folk music at beer gardens, wine festivals and inns; among their keenest admirers were Richter, Brahms, Johann Strauss and Emperor Franz Josef. Although these groups dated back to the Middle Ages, when they were used to spread music and news up and down the banks of the Danube, by the late nineteenth century they were called Schrammel quartets. The clarinet was replaced in 1893 by the accordion.
