Thoughout the east, much of the music was thought to be  centered around what is called a nuclear melody or nuclear theme. This now  appears to not be a clear as once thought.
The concept was a fixed melodic sequence in which traditionally different instruments take up different  levels of presenting or elaborating this outline, usually determined by preexisting rules or possibly one could say roles. The concept behind this group is to dispel with these roles and for the time being allow a more democratic equality between the parts.  Each player is directed to play certain notes at certain times ( this being the nuclear theme) but between the sounding of these tones, one can embellish this nuclear theme as ones instincts leads one. It is understood that the goal is ensemble playing as opposed to the group being a back up for soloist, although this option is open. Hopefully the process will determine the future and direction of this music and it is hope that a certain critical
imagination will help develop a freedom of expression that benefits the whole.
