• Wolfgang Amadeus Mozart – Eine kleine Nachtmusik, K525
• Pyotr Ilyich Tchaikovsky (edited by W Fitzenhagen) – Variations on a Rococo Theme, op33
• Wolfgang Amadeus Mozart – Symphony no40 in G minor, K550

Why are variations on a theme such a popular art-form – for composers, at least? Elgar famously used them, in his Enigma Variations, to paint portraits of his closest friends. Bach wrote the incomparable Goldberg Variations to assuage insomnia. And some – including Czerny, Brahms and Britten – composed a collection to pay tribute to those that have inspired or tutored them (respectively: Beethoven, Schumann and Bridge – but not exclusively).

The variation is one of the oldest musical forms: even being found within the keyboard works of William Byrd (c1540-1623). Its development is also intimately linked with that of the concerto: from the earliest concerti grossi, through Handel and JC Bach, to Franck’s Variations symphoniques for piano and orchestra – and, of course, this concert’s Rococo Variations.

Its possibilities are inexhaustible. If you require proof: one of the most popular themes used for ‘alteration’ is that of Paganini’s Caprice no24 in A minor for violin. Not only does this prototype itself include eleven variations; but many, many musicians – including Brahms, Lutosławski, and, most notably, Rachmaninoff – have created wonderfully transformative sequences of their own.

Julian Lloyd Webber, our conductor today, has also recorded an album, simply entitled Variations, based on this theme: written for him by his brother, Andrew. I therefore wondered if he might have an answer. Why…?

Because, for a composer, it’s a big challenge: to be able to write a set of variations on one particular theme; and come up with very different ideas. Some of the ideas are so good… – you hear these Paganini variations: the way different composers approach them – it’s fascinating. For instance, Rachmaninoff turning the tune around and making an absolutely beautiful melody – that’s very, very clever! I do think Andrew was quite brave to choose that tune: because so many other famous pieces had come out of it. But he’s never shirked a challenge!

And so I think it works both ways: for the composer to demonstrate his technique, and what he can actually do with imagination and a simple theme; and also for the audience, who get to follow the changes through a theme that they hear many times during a piece of music.

Tchaikovsky, of course, opted to write his own theme. He may claim it as ‘Rococo’; but, in reality, it has more to do with his role model – the man he called his “musical Christ” – Mozart: whose inspirational works also begin and end today’s proceedings.
