Score  
 
Summary: 
Entry in the JongNBE "On the way to the New Year's Concert" composition competition 2007 for people under 18. This year's theme was "Night", and as such I chose the subject "Aurora Australis", better known as the Southern Lights. The fast outer sections represent the wonder of the continuous collision of particles in the Earth's athmosphere, the slow mid-section represents the wonderment it creates. 
It's scored for flute, oboe, Bb clarinet, alto saxophone, bassoon, trumpet in Bb, horn in F, tenor trombone, percussion (susp. cymbal + xylophone), four-hand piano, double bass & tape. 
The overall style can be summarized as impressionistic minalism gone horribly hyperactive. I regarded the whole ensemble as an "aura apparatus" in the fast outer sections. 
It came to win a place in the final round.
