Neil Brand's Sound of Song - exploring the secret behind popular songs - will launch the year-long season on Friday.
In May, Strictly judge Darcey Bussell will lend her dance expertise to BBC Young Dancer 2015's Grand Final, broadcast live from Sadler's Wells.
The former Royal Ballet principal said she was "delighted to be involved".
Brand's Sound of Song, on BBC Four, will explore the elements that come together to create great songs, from Elvis Presley's 'slapback' echo in Memphis to the tape loops used by The Beatles at Abbey Road.
Other highlights of the year include:
"Over the next 12 months we'll be offering everyone extraordinary access to some of today's great artists and performers," said the BBC's director general Tony Hall.
"When the BBC gets behind something, working closely with lots of others, we can offer opportunities like no one else."

The Saudis say they do not know who fired the mortars, or from where.
A small Shia militant group in Iraq, known as the Mukhtar Army, has claimed it carried out the attack, although this cannot be confirmed.
The group said it was a warning to Saudi Arabia to stay out of Iraq's affairs.
The militia's commander, Wathiq al-Batat, told Reuters that the goal of the attack "was to send a warning message to Saudis to tell them that their border stations and patrol are within our range of fire".
The mortars fell in an uninhabited area near Hafr al-Batin in the kingdom's Eastern Province.
The mortar fire comes two days after suicide bombers killed more than 20 people outside the Iranian embassy in the Lebanese capital, Beirut.
On Thursday Saudi Arabia advised its citizens to leave Lebanon following those bombs.
The continuing civil war in Syria is fuelling increased tensions between nations in the region.
Saudi Arabia, which is largely Sunni, backs the rebels fighting to overthrow President Bashar al-Assad, whereas Shia Iran and Shia militias in Iraq and Lebanon back the president.
The BBC has launched The Year of Song and Dance 2015, which will include new programmes and live performances on BBC Two, BBC Four and Radio 3.
