an amino acid sequence according to the identified triplet codon series and conveys information related to the determined amino acids in a signal in one embodiment the harmonic sequence generator determines a series of chords according to the determined amino acid the harmonic information can be used by the melodic sequence generator to develop a melodic sequence further the harmonic sequence generator can identify chemical proerties that are associated with the determined amino acids the melody and harmony generated are then processed into a music signal by a music signal generator as shown in fig2 in one embodiment a melodic sequence is produced from the decoded dna sequence by assigning each nucleotide to a chord position converter the chord information is adjusted by an internal adjuster to produce a series of notes to generate a melodic sequence the adjuster may use harmonic sequence information to assign notes in the melody as chord tones or passing tones as shown in fig3 in one embodiment a harmonic sequence is produced from the decoded dna sequence by classifying each amino acid identified from the dna sequence the classification can be according to a chemical property such as u201c hydrophobic u201d or acidity and or simply by the amino acid name the classification data is converted into chord types by a chord type selector that selects chord roots to produce a harmonic sequence at the same time.
