She was recently named the Reinbert de Leeuw Professor of Music at London's Royal Academy of Music and has been visiting professor at the Juilliard School in New York.

Paul Dukas (1865-1935) L'apprenti sorcier L'apprenti sorcier (The Sorcerer's Apprentice) is the most famous work by the French composer Paul Dukas. It premiered in May 1897 in Paris with the composer himself conducting. The piece is based on Goethe's poem Der Zauberlehrling, about a sorcerer who leaves his apprentice to fetch water. But instead of doing it himself, the apprentice conjures up a broom to do the job for him. Dukas illustrates the broom with a rhythmic theme in the bassoon. The water is depicted through leaps and splashing cymbals. But the apprentice is not fully trained and loses control of the situation. The broom never stops fetching water. The room floods. The apprentice tries to chop the broom in half with an axe, which only gives rise to more brooms. A contributing factor to the music's great popularity was Walt Disney's animated film Fantasia from 1940, starring Mickey Mouse. Dukas' romantic and magical works stand today as a clear precursor, along with Korngold and Holst, to John Williams' shimmering film music.

Charles Ives (1874-1954) The Unanswered Question The Unanswered Question by Charles Ives is a work as mysterious as it was ahead of its time. From its composition in 1908, it took until 1946 before it was first performed. Today it is one of his best-known works. The piece is a kind of collage in three layers. The first layer, the strings, forms a slow, simple and tonal background. It represents the “silence of the druids”. On top of this, a lone trumpet returns with a short atonal motif. It is the “eternal question of existence”. The trumpet is in turn accompanied by woodwinds that, equally atonally, but increasingly faster, louder and more eager, try to answer the trumpet’s question – in vain. The question remains unanswered. The strings continue as if nothing has happened. How the “question” of existence has been interpreted has varied. The piece appears everywhere, from the war film The Thin Red Line to A Quiet Passion about the poet Emily Dickinson. It also gave name to Leonard Bernstein's lectures on the existence or non-existence of tonality. One theory is that Ives' title is taken from the poem The Sphinx by Ralph Waldo Emerson. The clash between the tonal and the atonal would then reflect the relationship between the spiritual and the physical – and how they actually belong together. A question without answer, but one that we cannot help asking again and again.
