The main sonic material of the work consist of a novel adaptation of sieve algorithm - as first introduced by Iannis Xenakis - seamlessly integrated with microsound synthesis (pulsar synthesis and wavesets), and distortion product otoacoustic emission (DPOAE).​

The term sieve (in phonetic description /sɪv/) is a metaphor for a process that selects certain sets by filtering specific intervals, particularly by means of the modulo operation. The sieve theory is a means of designing grids of diverse kinds whether in pitch, time, or another parameter through an application of logical operators (union, intersection, symmetrical difference etc).
