The Rossini Opera Festival participated in the Opera Europa summer conference, held at the Opernhaus Zurich from 28 to 30 June. The theme of the meeting was: Measuring the Arts. During the current season, Opera Europa has been encouraging its members to share performance data by means of two surveys. Both these measurements are quantitative. Is it also possible to measure quality? The summer conference explored this issue, and attempted to discover solutions which may be of practical use to the member theatres now and in the future.
