Written when the composer was just 12, Wolfgang Amadeus Mozart’s La Finta Semplice qualifies as a real rarity. After a performance the year following its composition, it dropped from the repertoire and was not staged again until modern times. That Musica Viva’s recent production at Hong Kong’s City Hall was a premiere seems beyond doubt, the only question being over how large a geographical area.

Reviewing a world premiere can be a privilege, albeit a somewhat daunting one. This first production of Beauty and Sadness, a new opera by Elena Langer to an English-language libretto by David Pountney, based on the 1975 novel by no less than Nobel Prize-winning Japanese author Yasunari Kawabata, is one of the most significant musical events to take place in Hong Kong in quite some time.

Opera Hong Kong’s summer semi-staged performances showcase local singers; this year’s production was Wolfgang Amadeus Mozart’s Die Zauberflöte. The fact that this work is more commonly known by its English name, The Magic Flute, is an indication that it is somewhat unusual: it’s known as a “singspiel”, or “sing-play”, which, like a musical, has spoken dialogue between the singing.
