Iridessi

Program Note: "Iridessi as an embodiment of life and light. The piece begins with a shimmering small light from the percussion instruments and grows into a luminous and vibrant dance of discovery. Throughout the work, different club-type beats in the winds and percussion are used to give Iridessi the life it needs. I wanted to display the different types of colors associated with light- from warm to harsh and pastel colors to saturated palettes. Finally, at the end of the piece, after this electric dance from the ensemble, the music evaporates into the air, leaving only the metallic instruments to fade away into the iridescent and invisible." - Katahj Copley

Contrast, Texture: The composer layers musical elements with different functions (melody, counter-melody, harmony, rhythm) in different parts of the ensemble. The fast, energetic rhythmic patterns are often contrasted when combined with sustained melodic lines. 

Ostinato: A repeated two-note figure between the notes E and F are heard throughout the piece. The first instance is in the Notable Passages below. The rest are listed here:
