The obvious one for me is music because it has been my life and career. However, nothing is completely separate from everything else so l would say that English and maths were equally important. History is another important subject because it means that a piece of music can be placed in the context of the time it was written, which helps to bring it to life. Finally, French and German. Although Italian is the lingua franca of music, many composers have written instructions in their own language. Sadly not very often in English although Percy Grainger, the early twentieth century composer of Country Gardens fame, tried it. I love his names for the string instruments. Instead of first and second violins, viola and ‘cello, he called them first fiddle, second fiddle, middle fiddle and bass fiddle.
