Do you know means of the word “Ambient”? I studied it came into use as musical genre “ambient music” named by Brian Eno who is English musician.
Descriptions from English Wikipedia, “Ambient music” is defined as like musical genre that focuses largely on the timbral characteristics of sounds, often organized or performed to evoke an “atmospheric”, “visual” or “unobtrusive” quality. From my image to this genre, it’s slow tempo, without lyric and like easy listening. “Ambient” is an English word, so for me, a Japanese guy, not native English speaker, it’s unnatural sound. Therefore, I associated the means of “Ambient” with the feelings of “Ambient music”. However, still it’s vague. I need to define it properly for using it in my logic.
