Ever the inventor, Haydn messed about with all sorts of formats you might be aware of. Did you know, for example, that he wrote Flötenuhrstücke, Hob. XIX:1-32, a series of works for the “flute clock”—a kind of mechanical organ? Or that he composed 123 trios for the nowadays all-but-unknown baryton—the favorite instrument of one of his aristocratic bosses? Or that he created 15 operas, many of which are hardly performed, even today? And that’s before we even get into the lesser-known of his 104(!) symphonies. You’re in for a treat with this one.
