even as few as four on some occasions, as indicated by the clarinet and horn bands of England and France. The clarinet was the preferred treble instrument in the west, while the Germans and Austrians generally preferred oboes. By the early 1780's the most common instrumentation, known as the Vienna tradition, consisted of 2 oboes, 2 clarinets, 2 horns, and 2 bassoons, or more concisely, 2222.2 According to tradition, in 1763 Frederick the Great was first to standardize his military bands into the octet, from which Harmonie developed. However, there seems to be no reference to prove such a claim. In fact, Roger Hellyer, a leading authority on Harmoniemusik, found no mention of clarinets in Berlin before the 1791 wedding of the Duke of York to Princess Friederike, for which Rosetti was commissioned to write two partitas for 2222.3 While eight players became the norm, there were notable exceptions. Instrumentation in the 19th century required up to twelve players, perhaps due to the increased harmonic demands of music of the Romantic period. On the occasion of the coronation of Kaiser Joseph II at Pressburg, the Harmonien of Prince Grassalkowitz and Prince Esterhazy combined to perform a piece for 21 wind instruments written by Georg Druschetsky.4
