Electronic music is a blanket term used to describe music that generally is made using electronic instruments (such as drum machines or synthesizers) or uses electronic equipment to make the sound. Techno Music can be described as organic-sounding, which means it sounds like something you would hear in nature and not with synthetic processes applied; whereas synthpop has elements of both synths and pop--so there's an element of artificiality but also some "natural" tendencies present due to vocals/instruments such as guitars.
