1 Free jazz almost by definition is free of such structures, but also by definition (it is, after all, jazz as much as it is free) it retains much of the language of earlier jazz playing. 2  It is therefore very common to hear diatonic, altered dominant and blues phrases in this music.
The main overall nuclear fusion reaction is the fusion of four hydrogen atom nuclei to form a bigger nucleus of a helium atom i.e. 4 1H1 $\rightarrow$ 4He2 + 2 0e+1+ energyi.e., 4 Hydrogen nuclei -----> Helium nucleus + 2 positrons + energy.
When the temperature in the core reaches about 100 million degrees, the helium will begin to fuse into carbon by a reaction known as the triple-alpha process, because it converts three helium nuclei into one carbon atom.This generates a great deal of heat.n heavier stars, the oxygen can in turn fuse with the helium to make neon.) Helium fusion produces only 9% as much energy per kilogram as hydrogen fusion, so energy-wise, the Sun continues to be mainly a hydrogen reactor. 90% of its luminosity still comes from burning hydrogen.
