Symphony, K. 19b (Mozart) symphonies K. 16 and K. 19 (strings, 2 oboes, and 2 horns). In his third edition of the Köchel catalogue, he dated it to early 1765 in London, and opined that the incipit showed the influence of J. C. Bach's symphonies. His remarks were copied unchanged by the sixth edition of the Köchel catalogue. Neal Zaslaw agreed that the opening was characteristic of J. C. Bach in his book "Mozart's Symphonies", but questioned if this was a legitimate method of dating works, given that the seven symphonies of J. C. Bach beginning in this march-like way were written later than
Large numbers If we need many such functions we can better number them instead of using a new letter every time, e.g. as a subscript, so we get numbers of the form formula_81 where "k" and "m" are given exactly and n is an integer which may or may not be given exactly. Using "k"=1 for the "f" above, "k"=2 for "g", etc., we have (10→10→"n"→"k") = formula_82. If "n" is large we can use any of the above for expressing it. Thus we get a nesting of forms formula_83 where going inward the "k" decreases, and with as inner argument a
