Ftir-based Sonification of Genomic Dna — Sonic Array of Rhythmic Alleles

Abstract This study introduces Sonic Array of Rhythmic Alleles (S.A.R.A.), an interdisciplinary framework converting FTIR spectra of genomic DNA into structured musical works. DNA from Peripheral Blood Mononuclear Cells is analyzed; interferograms are recovered via Inverse Fast Fourier Transform. Interferogram periodicities, intensities, and spacings map to pitch, dynamics, and rhythm using data science and music theory. Experiments with clustering and scaling factors evaluate tonal diversity. Sonification reveals vibrational traits linked to DNA conformation, with musical parameters maintaining spectral fidelity. Genomic features are differentiated through timbral acoustics. The work demonstrates how cross-domain sonification bridges STEM and arts to expand scientific interpretation and creative engagement, suggesting future integration of machine learning and cross-cultural tuning.
