The monumental achievement of Sibelius as a symphonist ended with his Sixth and Seventh Symphonies, written in 1923 and 1924. An eighth was destroyed, perhaps unsuited to a world, something of the sorrow of which had been finally expressed in the preceding work. His incidental music for a notable Danish performance of Shakespeare’s play The Tempest in 1925 resulted in two concert suites. The Second of these includes musical portraits of Prospero and Miranda and evokes the magic spirit of Prospero’s island.
