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.
But stars that are a couple of times more massive than the sun can keep going. After the helium is used up, the core contraction produces temperatures approaching one billion degrees. Now, the carbon and oxygen can start fusing to form even heavier elements: sodium, magnesium, silicon, phosphorous, and sulfur.
