Katarina Miljkovic: For Amy (2010)
The piece is my first attempt to compose in Bohlen-Pierce sound spectrum. After initial trials, beautiful sonorities began to emerge. All aspects of the musical structure, pitch, time and rhythm are based on the proportions 1:3:5:7:9:15. The center of symmetry is A 440, with duration of 1 second. The number of sound structures, repeating throughout the piece, are relating to the center and mirroring each other. Electronic part is generated in Mathematica, a perfect tool to get the exact proportions, and then processed. The composition is written for Amy Advocat whom I’ve known first as an undergraduate student at NEC and then as a brilliant professional performer.
