Creating tension

Creating  tension is essential , because if your music  just goes on with no contrast in a linear motion it will be real boring  and cold.

So create some tension  by taking out a few bars of some music elements before  some changes  happen
A few bars of bassline,add a few percussion  hits ,or take out a small bar of all music elements then re introduce a brand new section
Or bring back a main riff with main chorus but maybe this time play the main riff with different  instrument, in new key ,and new melody pattern. The possibilities  are endless  and remember  there is no right or wrong  in music so if it sounds good do it!
