Synthesizers are the bedrock of modern electronic music. The relation of the sounds they make to the music of the day is something that's always fascinated me: could certain genres have happened without the specific sounds of a specific synth to drive them? Would some styles we have today never exist, or would other ways to create the effects, moods and vibes have been discovered? It's an unanswerable question as we can't rewind history, but what can be said is there are a number of influential synths that have played an absolutely fundamental role in modern music and some genres even depend 100% on one particular model of synth.
