Program Notes:
The theme of light—its radiance, frequency, variety in colors, and intensity—has occupied my mind for quite some time. In previous compositions such as the Nocturne and Gleams from the Bosom of Darkness, I have endeavored to portray this visual image of light intensities in musical sounds. Therefore, when Maestro Ariel Zuckermann approached me to write a new work for the Georgian Chamber Orchestra with the theme of the Aurora Borealis in mind, I became immediately enthusiastic.
Aurora Borealis, also known as the Northern Lights, is an astronomical phenomenon in which light displays in the sky in various colors, usually observed in darkness at polar zones.
Technically speaking, auroras occur when charged particles from Earth’s magnetosphere collide with atoms and molecules in Earth’s upper atmosphere. These collisions electronically excite atoms and molecules in the upper atmosphere, creating gas-light emissions. Depending on the type of gas emission, green, red, blue, or violet colors appear. Therefore, although the viewer may perceive a static visual effect in the sky, there is much activity and intensity behind the scenes. This static activity, along with the ever-changing forms, light hues, and shades, is what I intended to portray musically in this piece, adding to it the mystic aura of this incredible phenomenon, which has rightfully found its way into many mythologies.
Aurora Borealis was written for the Georgian Chamber Orchestra, with Ariel Zuckermann as music director, and is dedicated to them.
