Dr. Susumu Ohno developed a system in 1986 to translate DNA sequences into musical scores, pioneering the concept of Protein music. A distinguished geneticist at the Beckman Research Institute of the City of Hope, Dr. Ohno realized that the “all-pervasive principle of repetitious recurrence” serves as the core foundational structure for both genetic evolution and musical composition.
The Scientific and Musical Premise Dr. Ohno noted that genes evolve primarily through duplication and subsequent diversification, meaning DNA is packed with repeating patterns. He argued that classical Western music shares this exact mathematical foundation, relying on repeating motifs, intervals, and themes to build complex arrangements out of simple blocks.Dr. Ohno believed that the “...all-pervasive principle of repetitious recurrence governs not only coding sequence construction but also human endeavor in musical composition.”,
Dr. Ohno created a standard formula to convert chemical data into a musical staff:The Scale: He utilized an 8-note diatonic scale.
Molecular Weights: He assigned pitch based on the molecular weights of the four nucleotide bases. He placed the heavier molecules in lower positions on the musical staff and lighter molecules in higher positions.
The Assignment: Each of the four DNA bases (Adenine, Cytosine, Guanine, and Thymine) was assigned two distinct positions to span a full octave. For example, a common mapping assignment translated G to A, T to C, C to G, and A to D.Timing and Rhythm: To add musical balance, the duration of the notes was dictated by the triplets (codons) that code for specific amino acids.
Famous Examples of His TranscriptionsWhen the genetic code was transformed using this formula, the resulting compositions did not sound chaotic; instead, they bore striking resemblances to classical masterpieces:
The Cancer Gene: When Ohno transcribed the SARC oncogene (a cancer-causing gene), the melody closely mirrored Chopin's Funeral March.
The Glucose Enzyme: The translation of phosphoglycerate kinase (an enzyme that breaks down sugar) yielded a soothing melody. When recorded by a violinist, the resulting piece acted as a lullaby
