Wagner's endlessly unresolved harmonies in Tristan and Isolde influenced composers for decades but it’s the emotional charge they convey that hits home.

Strauss' Four Last Songs sum up his lifelong love affair with the soprano voice and bid farewell to his composing career in music of rare beauty. The Philharmonia was the orchestra for their world première in 1950, while tonight’s soloist won the Song Prize at the BBC Cardiff Singer of the World competition.

Tchaikovsky's Sixth Symphony has probably been written about more than the other five combined, but whatever its significance in the composer’s life, its overwhelming impact is not in doubt. From the uneasy first movement to the groundbreaking slow finale, it wears its heart on its sleeve.

The Philharmonia Orchestra is Anvil Arts' Orchestra in Partnership.
