As for several previous years, I have tallied my opera and concert performances by composer. There are always slightly difficult cases, but in general, I have included as opera something performed as such, i.e. staged, even when the work is not. Hence the Deutsche Oper's St Matthew Passion on Good Friday counts, but the St John Passion the day before in the Thomaskirche does not. One point per composer per performance; so Il trittico would count as one, as would a lone performance of Gianni Schicchi, though Puccini and Ravel would both receive a point if there were a double-bill of Schicchi with L'Heure espagnole (which there wasn't). The Ring, however, counts as four, as did performances of two Gluck operas in the same evening. Concert performances of opera I have counted as opera, but obviously not as both. When a few opera excerpts by Salieri were used in a prologue to a performance of Rimsky Korsakov's Mozart and Salieri, I counted them under 'concert', since it seemed too much of a stretch to describe them as an opera and they had to go somewhere; they arguably might have gone here, though.
No huge surprises for opera in the higher ranks. Two Rings, one at Berlin's Deutsche Oper, one at its Staatsoper, plus a visit to Bayreuth, ensured the winner. It was a pleasant surprise, though, to see Rimsky-Korsakov come so high with three different works, which must be the most I have ever seen in a single year. And there is a good array of single-performance composers.
