The enthusiastic cry of “Whooa!” went up after the first movement of Mozart’s captivating Jupiter Symphony.

How vulgar. It is just not done in polite circles to applaud, let alone shout praise, until the end of all the movements in a piece.

In the ornate surroundings of Brighton’s Royal Pavilion music room it was a humorous set-up to illustrate Peter Seddon’s amusing Quiet Please history of concert manners.

Until the early 20th century, audiences were prone to eating, drinking, chatting, belching and snoring during concerts.

But they could not match the much-later spoiling efforts of about 50 schoolchildren who, immediately recognising a section of Rossini’s William Tell Overture, shouted in unison "The Lone Ranger!".

Rossini, who once visited the same room, would have appreciated the way the whole of the Sussex Symphony Orchestra executed his prank of starting the Overture To The Italian Girl In Algiers with seductive gentility, only to open up with all barrels a few bars in.

The orchestra, under conductor Rebecca Miller, displayed real power moments in Schubert’s Fifth Symphony and the Mozart.

With woodwinds in most beguiling form, they also showed the lightness of a soufflé in the rich surroundings, during the gentler passages.
