A synthesizer is something that is used in techno music. It is an electronic instrument capable of creating a range of sounds by generating and combining signals of different frequencies. There are three main types of synthesizers which operate differently: analog, digital and software-based. Rather than creating direct sounds, synthesizers create electrical signals which are processed through headphones or a loudspeaker.
Synthpop is a subgenre of New Wave music. In Synthpop, the synthesizer is the dominant musical instrument that is used. It is associated with the era between the late 1970s and early to middle 1980s however it has continued to exist and develop even up to this day. The German group Kraftwerk and Japanese group Yellow Magic Orchestra are said to pioneer this style of music, however a lot other musicians have improved to the original style.
