Define 'synthesizer' in music production.

A synthesizer is defined as an electronic instrument that generates audio signals. This instrument creates sound through various means, such as oscillation, modulation, and waveform manipulation, allowing musicians and producers to generate a wide range of audio textures and timbres. Synthesizers can replicate traditional instruments or create completely unique sounds that are not possible with acoustic instruments.

The other provided definitions are not applicable to synthesizers. Mixing sound pertains to audio production processes involving combining different audio tracks, while composing music refers to the act of writing or arranging music. Additionally, music genres categorize styles of music, but a synthesizer itself does not define a genre; rather, it can be utilized across multiple genres. Understanding what a synthesizer does helps clarify its role in music production, emphasizing its importance in contemporary music creation.
