In 1759, at the age of 27, Haydn gained his first secure musical appointment as Kapellmeister and Kammercompositeur to Count Morzin, who divided his time (as Haydn was now also required to do) between Vienna and his castle at Lukavec in Bohemia. At least a dozen of Haydn’s symphonies surface from the couple of years spent with Morzin. Their history is inevitably sketchy and, as ever with Haydn, the accepted numbering bears little relationship to their true chronology. The earliest of the four symphonies presented here, for example, are numbers 10 and 11. Neither was composed later than 1761, thus making them contemporary with numbers 1 to 5 (recorded on Helios CDH55111), yet with 15, 18, 27, 32, 33, 37 and ‘A’ pre-dating 6, 7 and 8 (on Helios CDH55112), his first works for Eszterháza.
