In this group the mineral is held together by the attraction between silica tetrahedra and other positive ions. Olivine and Garnet are examples of minerals within the independent tetrahedra group. Single chain silicates contain silica tetrahedra that are linked up in a chain by sharing two oxygen atoms. The most common single chain silicate is pyroxene. Double chain silicates form by sharing either two or three oxygen.
Time signatures are separated first by whether it is simple or compound. Then by whether it is a duple, triple, quadruple, quintic etc. Duple meters are grouped in 2.. 2/2, 2/4, 2/8 are all examples of simple duple meters. 6/8 would be an example of a compound duple meter as it still a grouping of two, but has 6 beats in one measure.
