Reykjavík Opera Days runs from 25 October to 1 November. Fourteen productions are listed here, across twenty-three performances and ten places. On the first morning Bálrautt teppi úr bútasaum, a new opera for children, plays twice at the Nordic House.

Where the singing happens matters more here than at most festivals. A classical singer works without a microphone, so the space around the voice is part of what you hear, and Reykjavík Opera Days keeps moving the voice: Norðurljós in Harpa, the Small Stage at the Reykjavík City Theatre, Tjarnarbíó, Salurinn in Kópavogur, the Free Church beside the pond, the Nordic House, a town square in Garðabær, and the water itself. A soprano is drawn across Tjörnin, the pond, and on the two evenings after across Árbæjarlaug Pool and Alftanes Swimming Pool, in a dress built from umbrellas that begins to glow as the light goes.

Bartók's only opera, Bluebeard's Castle, is staged twice in Norðurljós, sung in Hungarian by an Icelandic cast. hinÓperan brings 27, Ricky Ian Gordon and Royce Vavrek's opera about Gertrude Stein and Alice B. Toklas, to the Litla svið in English; two of its five performances belong to the festival and three run on into November, after everything else has closed. A portrait of Kurt Weill crosses German, English, French and Icelandic in a single evening.

Five performances are free. Thirteen publish a price, from 3,900 to 8,950 krónur for general admission, and five publish nothing at all. Tickets are sold by tix.is, harpa.is and borgarleikhus.is rather than by us, and every event page names the seller before it sends you there.

What a performance is sung in is the thing this site exists to tell you. On this festival it can say less than we would like. Four of the fourteen productions have said what they are sung in. The other ten have not, and their pages read unconfirmed rather than guessing. No performance in the festival has confirmed whether there are surtitles. Icelandic houses largely do not provide them, which is worth knowing and is not the same as being told.

Everything is under Events, where a date range narrows the list to the days you are in the country.
