A keyboard is not a synthesizer itself, but it can be used to control a synthesizer. A synthesizer is an electronic instrument that generates sound through the manipulation of various factors such as frequency, phase, and envelope. It often includes a keyboard as a means of input, but it can also be controlled by other means like MIDI controllers or even your computer. The keyboard itself only produces a sound when a key is pressed, while a synthesizer can create a wide variety of sounds and timbres.
