Epigenetic Music

The term epigenetic refers to heritable changes in gene expression, and therefore, in the phenotype of a cell, that don’t imply modifications in the DNA sequence. Like many eukaryotic cells, bacteria also use epigenetic DNA modifications to control gene expression (i.e. methylation).

LacZ has been “translated” without modification in to music, but the melody makes little sense. That is why we are going to apply the epigenetic concept to music, by translating to the musical realm the modifications that occur in bacteria in order to regulate gene expression. That way, correct expression of the melody will be achieved by regulating notes the following way:

- Metilation. Represses gene expression, as it represses the expression of a musical note by reducing the original length.

- Hypermetilation. Silences promoters, and therefore, silences a musical note.

Finally, we will use a post-transcriptional control mechanism by sRNA that is used in certain bacteria to activate gene expression. In music, this mechanism can increase the length of a note.

Integral serialism is a musical current that arose mid-twentieth century in Europe and United States. It emerged as a novel type of musical annotation that can be considered a variation of Schönberg’s 12-tone music (an attempt to erase the system of tonality). The 12-tone music annotation system stipulates that a note cannot be used again until all other 11 notes of the chromatic scale are used. Serialism can be applied to the use of fewer than 12 tones, and the result is a musical piece comprising ordered sets. Before starting to compose, everything is set by default, yielding a musical composition far from traditional.

We could consider our musical composition as a variation of integral serialism, as it is also set by default, following a conserved DNA sequence: the LacZ gene. Therefore, we could call this annotation system: genomic serialism.
