Created by transcoding/sonifying a data set of the energy distribution of rock schist under slow compression. Composed for the Sounds of Matter: Call4Sounds competition (www.matter.soundsof.net/ferroic).

This music is inspired by the poetic nature in which Ferroic materials break. The semi-crystalline structure of Ferroic materials and their mathematically predictable, and subsequently functional, structural failures, find strong corollaries with music’s use of semi-symmetric pitch and rhythmic entities to create patterns of tension and release. Beyond this larger formal homology, all of the sounds in the piece were created by sonifying a data set of the energy distribution over time of a slow compression experiment on schist. With the data stored as a normalized audio buffer, I created pitched, percussive, and ambient sounds by taking the sine of data values accumulated at audio sampling rate. Ultimately, I leveraged the data to produce the overtone series of several low frequencies. Given the fractal nature of the data, this resulted in repeated melodic structures, such as the descending ½-step, descending fifth, ascending whole-step motif heard in the second section. Subsequent wave shaping, variable playback rates, and frequency modulation were used to create different timbres. The power-law distribution of the data was particularly suitable for creating the crashing/rending sounds heard in the first section. The data was also transcoded into spectral information and used to drive a subtractive synthesis process.

Although my main concerns and objectives for this music were artistic and aesthetic, I hope this music will also aid in the researcher’s goals of understanding the dynamics of domain walls in Ferroic materials and the mechanisms that lead to their functionality.
