    In this approach tri-nucleotides are processed in an analogous way to the biological rules of the genetic code (in which a codon consists of three consecutive bases coding for one of 20 amino acid building blocks of a protein). Each of 64 possible codons are mapped to one of 20 musical notes rather than amino acids, as is the STOP codon. Each of the three possible open reading frames is mapped to a separate instruments. In the absence of further DNA sequence annotation to indicate the actual reading frame of the sequence, each open reading frame (instrument) is voiced sequentially with equal bias.
