Each movement of this piece is based on a different number sequence – the "Look-and-say” sequence, the "Thue-Morse" sequence, and a list of the partitions of numbers 1 to 8. For each movement I constructed a unique and detailed algorithm for interpreting the sequence into music. In movement one, percussive instruments drone the Look-and-say pattern, while the different voices of the organ change pitch when reaching a specific number in the sequence. Movement two starts on a central pitch, then translates “0” in the binary Thue-Morse sequence to remain on the same pitch, and “1” to move by selected intervals. Movement three takes the partitions of 1 to 8 voice cluster chord, displaying how they can be divided and combined as the piece develops.
These sequences all have a repetitive quality, producing an almost minimalist like progression throughout the piece. It’s a very simple and mathematical process for the instrumentalists. Rather than complex virtuosic passages, the skill lies in the ability to count odd groupings of rhythms and play long repetitive phrases. The end result is something hypnotic and meditative. After a long period of listening, the music sits deep in the listener, allowing them to hear the number sequence in action.
