Ricercare (Inventions for data streams #2)

The structure of Ricercare is a reinterpretation of the original “ricercare” style of the late renaissance and early baroque period. Here the word “ricercare“ (Italian for “to research”) takes a double meaning: on one hand is the research the performer does to find the optimal connection between the flute and the sonification of the data stream in the basso continuo accompaniment; on the other, it refers to the scientific research work that has led to the data on which this composition is based. All the parts are directly based on the remix and sonification of the materials property data for Silicon, Germanium and Tin (Si1_ICSD_60389, Ge1_ICSD_181071 and Sn1_ICSD_53789 in AFLOWLIB.org), some of the group IVa elements of the periodic table. The flute part is built on the materials data mapped to pitch class sets (one of the output of the data manipulation algorithm). These pitch class sets are used in the original form found by the mapping procedure – no operation (translation, inversion or multiplication) is done on the sets. The rhythmic patterns oscillate between quasi-random sequences and continuous virtuosity runs as in a baroque solo section. The basso continuo is split in one harmonic and one percussive part. The harmonic part comes from the direct mapping of the materials data into MIDI note-on/note-off events streamed live through the DataPlayer app; the percussive section doubles the flute part in a rhythmic unison triggered by the flute through an audio-to-MIDI pitch recognition Max for Live patch.
