An electronic music-creating device that directly alters electric current to shape sound waves. They are often controlled with piano-like keys but in reality they can be controlled with many interfaces such as a guitar, wind instrument, or even something you don't directly touch like a theramin. It is likely that in the future, most synthesizers won't be controlled by a traditional keyboard as it is quite archaic in it's nature.
