In The Final Frontier, the composer explores different associations with the universe. Inspired by Stephen Hawking's (1942-2018) book Brief Answers to the Big Questions, the piece describes the wonders and dangers of the universe, the big questions about the smallest elements, and the possibility of space travel. The work consists of four movements. The first movement, 'Energy and Space', is the exposition of both main materials. With energy and space, a universe can be created. The second movement, 'The Great Unknown', is a fast section in which the materials are further explored and depicts the dangers of the universe, like supernovae and black holes. The third movement, 'The Big Questions', is a slow movement with different soloists and music of a reflective nature. Imagine how in the tiniest elements, whole dimensions could be rolled up. Also, a Dutch pioneer in cosmology is hidden in the notes. The fourth movement, 'The Final Frontier', is a big build-up to a majestic finale, portraying the excitement of space travel. The Final Frontier was the set test piece of the 3rd section at the Dutch National Brass Band Championships.
