Mercury in Transit – a celestial event for wind ensemble was commissioned by Halifax All-City Music, Nathan Beeler, Director. It was inspired by the transit of Mercury that occurred on May 9, 2016. The form of the work follows the trajectory of Mercury, first hurling though space with a comet-like tail hundreds of thousands of kilometres behind it, then reaching the event horizon, and finally completing its transit in front of the sun. The work is in four distinct sections: (1) The comet tail of Mercury, (2) Mercury, the planet, (3) the event horizon, and (4) Mercury in transit. The next transit of Mercury will be on November 11, 2019.
