The work of classical composers Mozart and Shostakovich is to dominate this year's BBC Proms, which marks the 250th and 100th anniversaries of their birth.
The Queen will attend a concert in her honour, with 250 children singing a special commission by Sir Peter Maxwell Davies and Poet Laureate Andrew Motion.
The celebration of classical music, now in its 112th season, will conclude with five parties in parks around Britain.
Each concert will also be available online for a week after transmission.
Among the highlights from Mozart's canon will be a new completion of his Mass in C minor conducted by Sir Charles Mackerras and Glyndebourne's Cosi fan tutte.
There will be a weekend of Shostakovich-related concerts involving Russian conductor Valery Gergiev and performances of eight symphonies.Elgar composition debuts
The Proms will also see the premiere of the sixth instalment of one of Elgar's Pomp and Circumstance Marches, 70 years after the composer's death.
The first march in the series, Land of Hope and Glory, is one of the traditions of the Proms, with flag-waving members of the public singing along to it each year at the season's Last Night.
Now, the last known piece from the marches will be heard for the first time, nine years after fragments of it were discovered in the library of the Royal School of Church Music.
It has been brought to life by composer Anthony Payne as one of more than 100 works which have never been performed before at the Proms.Amateur singers targeted
Also this year, there is an invitation to more than 800 amateur singers to perform in two separate concerts which will feature a new work by Britain's Orlando Gough, with a text by playwright Caryl Churchill about climate change.
The First Night of the Proms, on 14 July, will involve Jiri Belohlavek, who is taking over on that day as the chief conductor of the BBC Symphony Orchestra.
London, Belfast, Manchester, Swansea and Glasgow will host special Proms in the Park parties on 9 September, the season's Last Night.
Terry Wogan will be the main presenter of the event in London, which the BBC describes as being "an integral part of the UK's music calendar".
All Proms will be broadcast live on BBC Radio 3, with three weeks of concerts on BBC Four and selected others seen on BBC One - including the concert on 19 July marking the Queen's 80th birthday - and BBC Two.
The BBC's online Listen Again facility will also store the audio from each Prom for seven days.
As usual the Classical Source will be reviewing the concerts from this year's Proms season. For more information please visit the Proms website at www.bbc.co.uk/proms.
