Here are a few possible explanations for the origin of the term:
* Synthesizer: The term "synth" is short for "synthesizer," which is an electronic instrument that can create a wide variety of sounds.
* Pad: In music, a "pad" is a sustained or continuous sound that provides a background or foundation for other instruments or vocals.
* Combination: The term "synth pad" is a combination of "synth" and "pad," indicating that these sounds are created using a synthesizer and are used to provide a background or atmospheric texture.
Over time, the term "synth pad" has become a widely recognized and commonly used term in electronic music to describe these types of sounds.
