In the making of each musical track the following has been taking into consideration:
1. - Each genetic key corresponds to the same musical key selected for each one of the tracks (eg. A=la, g=sol, t=re, c=do); the GF presents a single pattern in linear sequences or two different sound patterns in overlapping sequences.
2. - The GF in all cases has been the musical basis in the form of rythm of keys that make the DNA sound ocasionally as a piano, harp, oboe or other instruments. In the two classical tracks, we have tried to adapt the GF to the style of the work composition, while respecting the structure and creative profile of the authors.
3. - The personal musical preferences of the individual have been given prioriy, in such a way that this project could be called as "music a la carte" from the GF of a given individual. We have reflected the musical personality of the individual using data known about him/her.
4. - Typically, at the beginning or end of each musical track we have reflected the individual's genetic character XX or XY, by translating it to two identical or different chords, respectively.
5. - The time of each track or score has always been maintained at the regular cardiac frequence (60-120).
